+# Contributing to LangChain
+
+Hi there! Thank you for even being interested in contributing to LangChain.
+As an open source project in a rapidly developing field, we are extremely open
+to contributions, whether it be in the form of a new feature, improved infra, or better documentation.
+
+To contribute to this project, please follow a ["fork and pull request"](https://docs.github.com/en/get-started/quickstart/contributing-to-projects) workflow.
+Please do not try to push directly to this repo unless you are maintainer.
+
+## 🗺️Contributing Guidelines
+
+### 🚩GitHub Issues
+
+Our [issues](https://github.com/hwchase17/langchain/issues) page is kept up to date
+with bugs, improvements, and feature requests. There is a taxonomy of labels to help
+with sorting and discovery of issues of interest. These include:
+
+- prompts: related to prompt tooling/infra.
+- llms: related to LLM wrappers/tooling/infra.
+- chains
+- utilities: related to different types of utilities to integrate with (Python, SQL, etc.).
+- agents
+- memory
+- applications: related to example applications to build
+
+If you start working on an issue, please assign it to yourself.
+
+If you are adding an issue, please try to keep it focused on a single modular bug/improvement/feature.
+If the two issues are related, or blocking, please link them rather than keep them as one single one.
+
+We will try to keep these issues as up to date as possible, though
+with the rapid rate of develop in this field some may get out of date.
+If you notice this happening, please just let us know.
+
+### 🙋Getting Help
+
+Although we try to have a developer setup to make it as easy as possible for others to contribute (see below)
+it is possible that some pain point may arise around environment setup, linting, documentation, or other.
+Should that occur, please contact a maintainer! Not only do we want to help get you unblocked,
+but we also want to make sure that the process is smooth for future contributors.
+
+In a similar vein, we do enforce certain linting, formatting, and documentation standards in the codebase.
+If you are finding these difficult (or even just annoying) to work with,
+feel free to contact a maintainer for help - we do not want these to get in the way of getting
+good code into the codebase.
+
+### 🏭Release process
+
+As of now, LangChain has an ad hoc release process: releases are cut with high frequency via by
+a developer and published to [PyPI](https://pypi.org/project/langchain/).
+
+LangChain follows the [semver](https://semver.org/) versioning standard. However, as pre-1.0 software,
+even patch releases may contain [non-backwards-compatible changes](https://semver.org/#spec-item-4).
+
+If your contribution has made its way into a release, we will want to give you credit on Twitter (only if you want though)!
+If you have a Twitter account you would like us to mention, please let us know in the PR or in another manner.
+
+## 🚀Quick Start
+
+This project uses [Poetry](https://python-poetry.org/) as a dependency manager. Check out Poetry's [documentation on how to install it](https://python-poetry.org/docs/#installation) on your system before proceeding.
+
+❗Note: If you use `Conda` or `Pyenv` as your environment / package manager, avoid dependency conflicts by doing the following first:
+1. *Before installing Poetry*, create and activate a new Conda env (e.g. `conda create -n langchain python=3.9`)
+2. Install Poetry (see above)
+3. Tell Poetry to use the virtualenv python environment (`poetry config virtualenvs.prefer-active-python true`)
+4. Continue with the following steps.
+
+To install requirements:
+
+```bash
+poetry install -E all
+```
+
+This will install all requirements for running the package, examples, linting, formatting, tests, and coverage. Note the `-E all` flag will install all optional dependencies necessary for integration testing.
+
+Now, you should be able to run the common tasks in the following section.
+
+## ✅Common Tasks
+
+### Code Formatting
+
+Formatting for this project is done via a combination of [Black](https://black.readthedocs.io/en/stable/) and [isort](https://pycqa.github.io/isort/).
+
+To run formatting for this project:
+
+```bash
+make format
+```
+
+### Linting
+
+Linting for this project is done via a combination of [Black](https://black.readthedocs.io/en/stable/), [isort](https://pycqa.github.io/isort/), [flake8](https://flake8.pycqa.org/en/latest/), and [mypy](http://mypy-lang.org/).
+
+To run linting for this project:
+
+```bash
+make lint
+```
+
+We recognize linting can be annoying - if you do not want to do it, please contact a project maintainer, and they can help you with it. We do not want this to be a blocker for good code getting contributed.
+
+### Coverage
+
+Code coverage (i.e. the amount of code that is covered by unit tests) helps identify areas of the code that are potentially more or less brittle.
+
+To get a report of current coverage, run the following:
+
+```bash
+make coverage
+```
+
+### Testing
+
+Unit tests cover modular logic that does not require calls to outside APIs.
+
+To run unit tests:
+
+```bash
+make tests
+```
+
+If you add new logic, please add a unit test.
+
+Integration tests cover logic that requires making calls to outside APIs (often integration with other services).
+
+To run integration tests:
+
+```bash
+make integration_tests
+```
+
+If you add support for a new external API, please add a new integration test.
+
+### Adding a Jupyter Notebook
+
+If you are adding a Jupyter notebook example, you'll want to install the optional `dev` dependencies.
+
+To install dev dependencies:
+
+```bash
+poetry install --with dev
+```
+
+Launch a notebook:
+
+```bash
+poetry run jupyter notebook
+```
+
+When you run `poetry install`, the `langchain` package is installed as editable in the virtualenv, so your new logic can be imported into the notebook.
+
+## Documentation
+
+### Contribute Documentation
+
+Docs are largely autogenerated by [sphinx](https://www.sphinx-doc.org/en/master/) from the code.
+
+For that reason, we ask that you add good documentation to all classes and methods.
+
+Similar to linting, we recognize documentation can be annoying. If you do not want to do it, please contact a project maintainer, and they can help you with it. We do not want this to be a blocker for good code getting contributed.
+
+### Build Documentation Locally
+
+Before building the documentation, it is always a good idea to clean the build directory:
+
+```bash
+make docs_clean
+```
+
+Next, you can run the linkchecker to make sure all links are valid:
+
+```bash
+make docs_linkcheck
+```
+
+Finally, you can build the documentation as outlined below:
+
+```bash
+make docs_build
+```

-## 🚀 What can I do with this
+## 🚀 What can this help with?
 
-This project was largely inspired by a few projects seen on Twitter for which we thought it would make sense to have more explicit tooling. A lot of the initial functionality was done in an attempt to recreate those. Those are:
+There are six main areas that LangChain is designed to help with.
+These are, in increasing order of complexity:
 
-**[Self-ask-with-search](https://ofir.io/self-ask.pdf)**
+**📃 LLMs and Prompts:**
 
-To recreate this paper, use the following code snippet or checkout the [example notebook](https://github.com/hwchase17/langchain/blob/master/docs/examples/demos/self_ask_with_search.ipynb).
+This includes prompt management, prompt optimization, generic interface for all LLMs, and common utilities for working with LLMs.
 
-```python
-from langchain import SelfAskWithSearchChain, OpenAI, SerpAPIChain
+**🔗 Chains:**
 
-llm = OpenAI(temperature=0)
-search = SerpAPIChain()
+Chains go beyond just a single LLM call, and are sequences of calls (whether to an LLM or a different utility). LangChain provides a standard interface for chains, lots of integrations with other tools, and end-to-end chains for common applications.
 
-self_ask_with_search = SelfAskWithSearchChain(llm=llm, search_chain=search)
+**📚 Data Augmented Generation:**
 
-self_ask_with_search.run("What is the hometown of the reigning men's U.S. Open champion?")
-```
+Data Augmented Generation involves specific types of chains that first interact with an external datasource to fetch data to use in the generation step. Examples of this include summarization of long pieces of text and question/answering over specific data sources.
 
-**[LLM Math](https://twitter.com/amasad/status/1568824744367259648?s=20&t=-7wxpXBJinPgDuyHLouP1w)**
+**🤖 Agents:**
 
-To recreate this example, use the following code snippet or check out the [example notebook](https://github.com/hwchase17/langchain/blob/master/docs/examples/demos/llm_math.ipynb).
+Agents involve an LLM making decisions about which Actions to take, taking that Action, seeing an Observation, and repeating that until done. LangChain provides a standard interface for agents, a selection of agents to choose from, and examples of end to end agents.
 
-```python
-from langchain import OpenAI, LLMMathChain
+**🧠 Memory:**
 
-llm = OpenAI(temperature=0)
-llm_math = LLMMathChain(llm=llm)
+Memory is the concept of persisting state between calls of a chain/agent. LangChain provides a standard interface for memory, a collection of memory implementations, and examples of chains/agents that use memory.
 
-llm_math.run("How many of the integers between 0 and 99 inclusive are divisible by 8?")
-```
+**🧐 Evaluation:**
 
-**Generic Prompting**
+[BETA] Generative models are notoriously hard to evaluate with traditional metrics. One new way of evaluating them is using language models themselves to do the evaluation. LangChain provides some prompts/chains for assisting in this.
 
-You can also use this for simple prompting pipelines, as in the below example and this [example notebook](https://github.com/hwchase17/langchain/blob/master/docs/examples/demos/simple_prompts.ipynb).
+For more information on these concepts, please see our [full documentation](https://langchain.readthedocs.io/en/latest/?).
 
-```python
-from langchain import Prompt, OpenAI, LLMChain
+## 💁 Contributing
 
-template = """Question: {question}
+As an open source project in a rapidly developing field, we are extremely open to contributions, whether it be in the form of a new feature, improved infra, or better documentation.
 
-Answer: Let's think step by step."""
-prompt = Prompt(template=template, input_variables=["question"])
-llm = OpenAI(temperature=0)
-llm_chain = LLMChain(prompt=prompt, llm=llm)
-
-question = "What NFL team won the Super Bowl in the year Justin Bieber was born?"
-
-llm_chain.predict(question=question)
-```
-
-**Embed & Search Documents**
-
-We support two vector databases to store and search embeddings -- FAISS and Elasticsearch. Here's a code snippet showing how to use FAISS to store embeddings and search for text similar to a query. Both database backends are featured in this [example notebook](https://github.com/hwchase17/langchain/blob/master/docs/examples/integrations/embeddings.ipynb).
-
-```python
-from langchain.embeddings.openai import OpenAIEmbeddings
-from langchain.faiss import FAISS
-from langchain.text_splitter import CharacterTextSplitter
-
-with open('state_of_the_union.txt') as f:
-    state_of_the_union = f.read()
-text_splitter = CharacterTextSplitter(chunk_size=1000, chunk_overlap=0)
-texts = text_splitter.split_text(state_of_the_union)
-
-embeddings = OpenAIEmbeddings()
-
-docsearch = FAISS.from_texts(texts, embeddings)
-
-query = "What did the president say about Ketanji Brown Jackson"
-docs = docsearch.similarity_search(query)
-```

-# Core Concepts
-
-This section goes over the core concepts of LangChain.
-Understanding these will go a long way in helping you understand the codebase and how to construct chains.
-
-## Prompts
-Prompts generically have a `format` method that takes in variables and returns a formatted string.
-The most simple implementation of this is to have a template string with some variables in it, and then format it with the incoming variables.
-More complex iterations dynamically construct the template string from few shot examples, etc.
-
-## LLMs
-Wrappers around Large Language Models (in particular, the `generate` ability of large language models) are some of the core functionality of LangChain.
-These wrappers are classes that are callable: they take in an input string, and return the generated output string.
-
-## Embeddings
-These classes are very similar to the LLM classes in that they are wrappers around models, 
-but rather than return a string they return an embedding (list of floats). This are particularly useful when 
-implementing semantic search functionality. They expose separate methods for embedding queries versus embedding documents.
-
-## Vectorstores
-These are datastores that store documents. They expose a method for passing in a string and finding similar documents.
-
-## Chains
-These are pipelines that combine multiple of the above ideas. 
-They vary greatly in complexity and are combination of generic, highly configurable pipelines and more narrow (but usually more complex) pipelines.

+# Deployments
+
+So you've made a really cool chain - now what? How do you deploy it and make it easily sharable with the world?
+
+This section covers several options for that.
+Note that these are meant as quick deployment options for prototypes and demos, and not for production systems.
+If you are looking for help with deployment of a production system, please contact us directly.
+
+What follows is a list of template GitHub repositories aimed that are intended to be
+very easy to fork and modify to use your chain.
+This is far from an exhaustive list of options, and we are EXTREMELY open to contributions here.
+
+## [Streamlit](https://github.com/hwchase17/langchain-streamlit-template)
+
+This repo serves as a template for how to deploy a LangChain with Streamlit.
+It implements a chatbot interface.

-# Using Chains
-
-Calling an LLM is a great first step, but it's just the beginning.
-Normally when you use an LLM in an application, you are not sending user input directly to the LLM.
-Instead, you are probably taking user input and constructing a prompt, and then sending that to the LLM.
-
-For example, in the previous example, the text we passed in was hardcoded to ask for a name for a company that made colorful socks.
-In this imaginary service, what we would want to do is take only the user input describing what the company does, and then format the prompt with that information.
-
-This is easy to do with LangChain!
-
-First lets define the prompt:
-
-```python
-from langchain.prompts import Prompt
-prompt = Prompt(
-    input_variables=["product"], 
-    template="What is a good name for a company that makes {product}?",
-)
-```
-
-We can now create a very simple chain that will take user input, format the prompt with it, and then send it to the LLM:
-
-```python
-from langchain.chains import LLMChain
-chain = LLMChain(llm=llm, prompt=prompt)
-```
-
-Now we can run that can only specifying the product!
-
-```python
-chain.run("colorful socks")
-```
-
-There we go! There's the first chain.
-
-That is it for the Getting Started example. 
-As a next step, we would suggest checking out the more complex chains in the [Demos section](/examples/demos.rst)

-# Setting up your environment
-
-Using LangChain will usually require integrations with one or more model providers, data stores, apis, etc.
-There are two components to setting this up, installing the correct python packages and setting the right environment variables.
-
-## Python packages
-The python package needed varies based on the integration. See the list of integrations for details.
-There should also be helpful error messages raised if you try to run an integration and are missing any required python packages.
-
-## Environment Variables
-The environment variable needed varies based on the integration. See the list of integrations for details.
-There should also be helpful error messages raised if you try to run an integration and are missing any required environment variables.
-
-You can set the environment variable in a few ways. 
-If you are trying to set the environment variable `FOO` to value `bar`, here are the ways you could do so:
-- From the command line:
-```
-export FOO=bar
-```
-- From the python notebook/script:
-```python
-import os
-os.environ["FOO"] = "bar"
-```
-
-For the Getting Started example, we will be using OpenAI's APIs, so we will first need to install their SDK:
-
-```
-pip install openai
-```
-
-We will then need to set the environment variable. Let's do this from inside the Jupyter notebook (or Python script).

+# Quickstart Guide
+
+
+This tutorial gives you a quick walkthrough about building an end-to-end language model application with LangChain.
+
+## Installation
+
+To get started, install LangChain with the following command:
+
+```bash
+pip install langchain
+```
+
+
+## Environment Setup
+
+Using LangChain will usually require integrations with one or more model providers, data stores, apis, etc.
+
+For this example, we will be using OpenAI's APIs, so we will first need to install their SDK:
+
+```bash
+pip install openai
+```
+
+We will then need to set the environment variable in the terminal.
+
+```bash
+export OPENAI_API_KEY="..."
+```
+
+Alternatively, you could do this from inside the Jupyter notebook (or Python script):
+
+```python
+import os
+os.environ["OPENAI_API_KEY"] = "..."
+```
+
+
+## Building a Language Model Application
+
+Now that we have installed LangChain and set up our environment, we can start building our language model application.
+
+LangChain provides many modules that can be used to build language model applications. Modules can be combined to create more complex applications, or be used individually for simple applications.
+
+
+
+`````{dropdown} LLMs: Get predictions from a language model
+
+The most basic building block of LangChain is calling an LLM on some input.
+Let's walk through a simple example of how to do this. 
+For this purpose, let's pretend we are building a service that generates a company name based on what the company makes.
+
+In order to do this, we first need to import the LLM wrapper.
+
+```python
+from langchain.llms import OpenAI
+```
+
+We can then initialize the wrapper with any arguments.
+In this example, we probably want the outputs to be MORE random, so we'll initialize it with a HIGH temperature.
+
+```python
+llm = OpenAI(temperature=0.9)
+```
+
+We can now call it on some input!
+
+```python
+text = "What would be a good company name a company that makes colorful socks?"
+print(llm(text))
+```
+
+```pycon
+Feetful of Fun
+```
+
+For more details on how to use LLMs within LangChain, see the [LLM getting started guide](../modules/llms/getting_started.ipynb).
+`````
+
+
+`````{dropdown} Prompt Templates: Manage prompts for LLMs
+
+Calling an LLM is a great first step, but it's just the beginning.
+Normally when you use an LLM in an application, you are not sending user input directly to the LLM.
+Instead, you are probably taking user input and constructing a prompt, and then sending that to the LLM.
+
+For example, in the previous example, the text we passed in was hardcoded to ask for a name for a company that made colorful socks.
+In this imaginary service, what we would want to do is take only the user input describing what the company does, and then format the prompt with that information.
+
+This is easy to do with LangChain!
+
+First lets define the prompt template:
+
+```python
+from langchain.prompts import PromptTemplate
+
+prompt = PromptTemplate(
+    input_variables=["product"],
+    template="What is a good name for a company that makes {product}?",
+)
+```
+
+Let's now see how this works! We can call the `.format` method to format it.
+
+```python
+print(prompt.format(product="colorful socks"))
+```
+
+```pycon
+What is a good name for a company that makes colorful socks?
+```
+
+
+[For more details, check out the getting started guide for prompts.](../modules/prompts/getting_started.ipynb)
+
+`````
+
+
+
+`````{dropdown} Chains: Combine LLMs and prompts in multi-step workflows
+
+Up until now, we've worked with the PromptTemplate and LLM primitives by themselves. But of course, a real application is not just one primitive, but rather a combination of them.
+
+A chain in LangChain is made up of links, which can be either primitives like LLMs or other chains.
+
+The most core type of chain is an LLMChain, which consists of a PromptTemplate and an LLM.
+
+Extending the previous example, we can construct an LLMChain which takes user input, formats it with a PromptTemplate, and then passes the formatted response to an LLM.
+
+```python
+from langchain.prompts import PromptTemplate
+from langchain.llms import OpenAI
+
+llm = OpenAI(temperature=0.9)
+prompt = PromptTemplate(
+    input_variables=["product"],
+    template="What is a good name for a company that makes {product}?",
+)
+```
+
+We can now create a very simple chain that will take user input, format the prompt with it, and then send it to the LLM:
+
+```python
+from langchain.chains import LLMChain
+chain = LLMChain(llm=llm, prompt=prompt)
+```
+
+Now we can run that chain only specifying the product!
+
+```python
+chain.run("colorful socks")
+# -> '\n\nSocktastic!'
+```
+
+There we go! There's the first chain - an LLM Chain.
+This is one of the simpler types of chains, but understanding how it works will set you up well for working with more complex chains.
+
+[For more details, check out the getting started guide for chains.](../modules/chains/getting_started.ipynb)
+
+`````
+
+
+`````{dropdown} Agents: Dynamically call chains based on user input
+
+So far the chains we've looked at run in a predetermined order.
+
+Agents no longer do: they use an LLM to determine which actions to take and in what order. An action can either be using a tool and observing its output, or returning to the user.
+
+When used correctly agents can be extremely powerful. In this tutorial, we show you how to easily use agents through the simplest, highest level API.
+
+
+In order to load agents, you should understand the following concepts:
+
+- Tool: A function that performs a specific duty. This can be things like: Google Search, Database lookup, Python REPL, other chains. The interface for a tool is currently a function that is expected to have a string as an input, with a string as an output.
+- LLM: The language model powering the agent.
+- Agent: The agent to use. This should be a string that references a support agent class. Because this notebook focuses on the simplest, highest level API, this only covers using the standard supported agents. If you want to implement a custom agent, see the documentation for custom agents (coming soon).
+
+**Agents**: For a list of supported agents and their specifications, see [here](../modules/agents/agents.md).
+
+**Tools**: For a list of predefined tools and their specifications, see [here](../modules/agents/tools.md).
+
+For this example, you will also need to install the SerpAPI Python package.
+
+```bash
+pip install google-search-results
+```
+
+And set the appropriate environment variables.
+
+```python
+import os
+os.environ["SERPAPI_API_KEY"] = "..."
+```
+
+Now we can get started!
+
+```python
+from langchain.agents import load_tools
+from langchain.agents import initialize_agent
+from langchain.llms import OpenAI
+
+# First, let's load the language model we're going to use to control the agent.
+llm = OpenAI(temperature=0)
+
+# Next, let's load some tools to use. Note that the `llm-math` tool uses an LLM, so we need to pass that in.
+tools = load_tools(["serpapi", "llm-math"], llm=llm)
+
+
+# Finally, let's initialize an agent with the tools, the language model, and the type of agent we want to use.
+agent = initialize_agent(tools, llm, agent="zero-shot-react-description", verbose=True)
+
+# Now let's test it out!
+agent.run("Who is Olivia Wilde's boyfriend? What is his current age raised to the 0.23 power?")
+```
+
+```pycon
+Entering new AgentExecutor chain...
+ I need to find out who Olivia Wilde's boyfriend is and then calculate his age raised to the 0.23 power.
+Action: Search
+Action Input: "Olivia Wilde boyfriend"
+Observation: Jason Sudeikis
+Thought: I need to find out Jason Sudeikis' age
+Action: Search
+Action Input: "Jason Sudeikis age"
+Observation: 47 years
+Thought: I need to calculate 47 raised to the 0.23 power
+Action: Calculator
+Action Input: 47^0.23
+Observation: Answer: 2.4242784855673896
+
+Thought: I now know the final answer
+Final Answer: Jason Sudeikis, Olivia Wilde's boyfriend, is 47 years old and his age raised to the 0.23 power is 2.4242784855673896.
+> Finished AgentExecutor chain.
+"Jason Sudeikis, Olivia Wilde's boyfriend, is 47 years old and his age raised to the 0.23 power is 2.4242784855673896."
+```
+
+
+`````
+
+
+`````{dropdown} Memory: Add state to chains and agents
+
+So far, all the chains and agents we've gone through have been stateless. But often, you may want a chain or agent to have some concept of "memory" so that it may remember information about its previous interactions. The clearest and simple example of this is when designing a chatbot - you want it to remember previous messages so it can use context from that to have a better conversation. This would be a type of "short-term memory". On the more complex side, you could imagine a chain/agent remembering key pieces of information over time - this would be a form of "long-term memory". For more concrete ideas on the latter, see this [awesome paper](https://memprompt.com/).
+
+LangChain provides several specially created chains just for this purpose. This notebook walks through using one of those chains (the `ConversationChain`) with two different types of memory.
+
+By default, the `ConversationChain` has a simple type of memory that remembers all previous inputs/outputs and adds them to the context that is passed. Let's take a look at using this chain (setting `verbose=True` so we can see the prompt).
+
+```python
+from langchain import OpenAI, ConversationChain
+
+llm = OpenAI(temperature=0)
+conversation = ConversationChain(llm=llm, verbose=True)
+
+conversation.predict(input="Hi there!")
+```
+
+```pycon
+> Entering new chain...
+Prompt after formatting:
+The following is a friendly conversation between a human and an AI. The AI is talkative and provides lots of specific details from its context. If the AI does not know the answer to a question, it truthfully says it does not know.
+
+Current conversation:
+
+Human: Hi there!
+AI:
+
+> Finished chain.
+' Hello! How are you today?'
+```
+
+```python
+conversation.predict(input="I'm doing well! Just having a conversation with an AI.")
+```

-# Calling a LLM
-
-The most basic building block of LangChain is calling an LLM on some input.
-Let's walk through a simple example of how to do this. 
-For this purpose, let's pretend we are building a service that generates a company name based on what the company makes.
-
-In order to do this, we first need to import the LLM wrapper.
-
-```python
-from langchain.llms import OpenAI
-```
-
-We can then initialize the wrapper with any arguments.
-In this example, we probably want the outputs to be MORE random, so we'll initialize it with a HIGH temperature.
-
-```python
-llm = OpenAI(temperature=0.9)
-```
-
-We can now call it on some input!
-
-```python
-text = "What would be a good company name a company that makes colorful socks?"
-llm(text)

+Modules
+-----------
+
+There are six main modules that LangChain provides support for.
+For each module we provide some examples to get started, how-to guides, reference docs, and conceptual guides.
+These modules are, in increasing order of complexity:
+
+
+- `Prompts <./modules/prompts.html>`_: This includes prompt management, prompt optimization, and prompt serialization.
+
+- `LLMs <./modules/llms.html>`_: This includes a generic interface for all LLMs, and common utilities for working with LLMs.
+
+- `Document Loaders <./modules/document_loaders.html>`_: This includes a standard interface for loading documents, as well as specific integrations to all types of text data sources.
+
+- `Utils <./modules/utils.html>`_: Language models are often more powerful when interacting with other sources of knowledge or computation. This can include Python REPLs, embeddings, search engines, and more. LangChain provides a large collection of common utils to use in your application.
+
+- `Chains <./modules/chains.html>`_: Chains go beyond just a single LLM call, and are sequences of calls (whether to an LLM or a different utility). LangChain provides a standard interface for chains, lots of integrations with other tools, and end-to-end chains for common applications.
+
+- `Agents <./modules/agents.html>`_: Agents involve an LLM making decisions about which Actions to take, taking that Action, seeing an Observation, and repeating that until done. LangChain provides a standard interface for agents, a selection of agents to choose from, and examples of end to end agents.
+
+- `Memory <./modules/memory.html>`_: Memory is the concept of persisting state between calls of a chain/agent. LangChain provides a standard interface for memory, a collection of memory implementations, and examples of chains/agents that use memory.

+Use Cases
+----------
+
+The above modules can be used in a variety of ways. LangChain also provides guidance and assistance in this. Below are some of the common use cases LangChain supports.
+
+- `Agents <./use_cases/agents.html>`_: Agents are systems that use a language model to interact with other tools. These can be used to do more grounded question/answering, interact with APIs, or even take actions.
+
+- `Chatbots <./use_cases/chatbots.html>`_: Since language models are good at producing text, that makes them ideal for creating chatbots.
+
+- `Data Augmented Generation <./use_cases/combine_docs.html>`_: Data Augmented Generation involves specific types of chains that first interact with an external datasource to fetch data to use in the generation step. Examples of this include summarization of long pieces of text and question/answering over specific data sources.
+
+- `Question Answering <./use_cases/question_answering.html>`_: Answering questions over specific documents, only utilizing the information in those documents to construct an answer. A type of Data Augmented Generation.
+
+- `Summarization <./use_cases/summarization.html>`_: Summarizing longer documents into shorter, more condensed chunks of information. A type of Data Augmented Generation.
+
+- `Evaluation <./use_cases/evaluation.html>`_: Generative models are notoriously hard to evaluate with traditional metrics. One new way of evaluating them is using language models themselves to do the evaluation. LangChain provides some prompts/chains for assisting in this.
+
+- `Generate similar examples <./use_cases/generate_examples.html>`_: Generating similar examples to a given input. This is a common use case for many applications, and LangChain provides some prompts/chains for assisting in this.
+
+- `Compare models <./use_cases/model_laboratory.html>`_: Experimenting with different prompts, models, and chains is a big part of developing the best possible application. The ModelLaboratory makes it easy to do so.

+Agents
+==========================
+
+Some applications will require not just a predetermined chain of calls to LLMs/other tools,
+but potentially an unknown chain that depends on the user input.
+In these types of chains, there is a “agent” which has access to a suite of tools.

+# Agents
+
+Agents use an LLM to determine which actions to take and in what order.
+An action can either be using a tool and observing its output, or returning to the user.
+For a list of easily loadable tools, see [here](tools.md).
+Here are the agents available in LangChain.
+
+For a tutorial on how to load agents, see [here](getting_started.ipynb).
+
+## `zero-shot-react-description`
+
+This agent uses the ReAct framework to determine which tool to use
+based solely on the tool's description. Any number of tools can be provided.
+This agent requires that a description is provided for each tool.
+
+## `react-docstore`
+
+This agent uses the ReAct framework to interact with a docstore. Two tools must
+be provided: a `Search` tool and a `Lookup` tool (they must be named exactly as so).
+The `Search` tool should search for a document, while the `Lookup` tool should lookup
+a term in the most recently found document.
+This agent is equivalent to the
+original [ReAct paper](https://arxiv.org/pdf/2210.03629.pdf), specifically the Wikipedia example.
+
+## `self-ask-with-search`
+
+This agent utilizes a single tool that should be named `Intermediate Answer`.
+This tool should be able to lookup factual answers to questions. This agent
+is equivalent to the original [self ask with search paper](https://ofir.io/self-ask.pdf),
+where a Google search API was provided as the tool.
+
+### `conversational-react-description`
+
+This agent is designed to be used in conversational settings.
+The prompt is designed to make the agent helpful and conversational.
+It uses the ReAct framework to decide which tool to use, and uses memory to remember the previous conversation interactions.

+    "\n",
+    "Most of the work in creating the custom LLMChain comes down to the prompt. Because we are using an existing agent class to parse the output, it is very important that the prompt say to produce text in that format. Additionally, we currently require an `agent_scratchpad` input variable to put notes on previous actions and observations. This should almost always be the final part of the prompt. However, besides those instructions, you can customize the prompt as you wish.\n",

+    "- input_variables: List of input variables the final prompt will expect.\n",

+How-To Guides
+=============
+
+The first category of how-to guides here cover specific parts of working with agents.
+
+`Load From Hub <./examples/load_from_hub.html>`_: This notebook covers how to load agents from `LangChainHub <https://github.com/hwchase17/langchain-hub>`_.
+
+`Custom Tools <./examples/custom_tools.html>`_: How to create custom tools that an agent can use.
+
+`Intermediate Steps <./examples/intermediate_steps.html>`_: How to access and use intermediate steps to get more visibility into the internals of an agent.
+
+`Custom Agent <./examples/custom_agent.html>`_: How to create a custom agent (specifically, a custom LLM + prompt to drive that agent).
+
+`Multi Input Tools <./examples/multi_input_tool.html>`_: How to use a tool that requires multiple inputs with an agent.
+
+`Search Tools <./examples/search_tools.html>`_: How to use the different type of search tools that LangChain supports.
+
+`Max Iterations <./examples/max_iterations.html>`_: How to restrict an agent to a certain number of iterations.
+
+`Asynchronous <./examples/async_agent.html>`_: Covering asynchronous functionality.
+
+The next set of examples are all end-to-end agents for specific applications.
+In all examples there is an Agent with a particular set of tools.
+
+- Tools: A tool can be anything that takes in a string and returns a string. This means that you can use both the primitives AND the chains found in `this <../chains.html>`_ documentation. LangChain also provides a list of easily loadable tools. For detailed information on those, please see `this documentation <./tools.html>`_
+- Agents: An agent uses an LLMChain to determine which tools to use. For a list of all available agent types, see `here <./agents.html>`_.
+
+**MRKL**
+
+- **Tools used**: Search, SQLDatabaseChain, LLMMathChain
+- **Agent used**: `zero-shot-react-description`
+- `Paper <https://arxiv.org/pdf/2205.00445.pdf>`_
+- **Note**: This is the most general purpose example, so if you are looking to use an agent with arbitrary tools, please start here.
+- `Example Notebook <./implementations/mrkl.html>`_
+
+**Self-Ask-With-Search**
+
+- **Tools used**: Search
+- **Agent used**: `self-ask-with-search`
+- `Paper <https://ofir.io/self-ask.pdf>`_
+- `Example Notebook <./implementations/self_ask_with_search.html>`_
+
+**ReAct**
+
+- **Tools used**: Wikipedia Docstore
+- **Agent used**: `react-docstore`
+- `Paper <https://arxiv.org/pdf/2210.03629.pdf>`_
+- `Example Notebook <./implementations/react.html>`_

+# Tools
+
+Tools are functions that agents can use to interact with the world.
+These tools can be generic utilities (e.g. search), other chains, or even other agents.
+
+Currently, tools can be loaded with the following snippet:
+
+```python
+from langchain.agents import load_tools
+tool_names = [...]
+tools = load_tools(tool_names)
+```
+
+Some tools (e.g. chains, agents) may require a base LLM to use to initialize them.
+In that case, you can pass in an LLM as well:
+
+```python
+from langchain.agents import load_tools
+tool_names = [...]
+llm = ...
+tools = load_tools(tool_names, llm=llm)
+```
+
+Below is a list of all supported tools and relevant information:

+# CombineDocuments Chains
+CombineDocuments chains are useful for when you need to run a language over multiple documents.
+Common use cases for this include question answering, question answering with sources, summarization, and more.
+For more information on specific use cases as well as different methods for **fetching** these documents, please see 
+[this overview](/use_cases/combine_docs.md).
+
+This documentation now picks up from after you've fetched your documents - now what?
+How do you pass them to the language model in a format it can understand?
+There are a few different methods, or chains, for doing so. LangChain supports four of the more common ones - and
+we are actively looking to include more, so if you have any ideas please reach out! Note that there is not
+one best method - the decision of which one to use is often very context specific. In order from simplest to
+most complex:
+
+## Stuffing
+Stuffing is the simplest method, whereby you simply stuff all the related data into the prompt as context
+to pass to the language model. This is implemented in LangChain as the `StuffDocumentsChain`.
+
+**Pros:** Only makes a single call to the LLM. When generating text, the LLM has access to all the data at once.
+
+**Cons:** Most LLMs have a context length, and for large documents (or many documents) this will not work as it will result in a prompt larger than the context length.
+
+The main downside of this method is that it only works one smaller pieces of data. Once you are working
+with many pieces of data, this approach is no longer feasible. The next two approaches are designed to help deal with that.
+
+## Map Reduce
+This method involves an initial prompt on each chunk of data (for summarization tasks, this 
+could be a summary of that chunk; for question-answering tasks, it could be an answer based solely on that chunk).
+Then a different prompt is run to combine all the initial outputs. This is implemented in the LangChain as the `MapReduceDocumentsChain`.
+
+**Pros:** Can scale to larger documents (and more documents) than `StuffDocumentsChain`. The calls to the LLM on individual documents are independent and can therefore be parallelized.
+
+**Cons:** Requires many more calls to the LLM than `StuffDocumentsChain`. Loses some information during the final combining call.
+
+## Refine
+This method involves an initial prompt on the first chunk of data, generating some output.
+For the remaining documents, that output is passed in, along with the next document, 
+asking the LLM to refine the output based on the new document. 
+
+**Pros:** Can pull in more relevant context, and may be less lossy than `MapReduceDocumentsChain`.
+
+**Cons:** Requires many more calls to the LLM than `StuffDocumentsChain`. The calls are also NOT independent, meaning they cannot be paralleled like `MapReduceDocumentsChain`. There is also some potential dependencies on the ordering of the documents.
+
+
+## Map-Rerank
+This method involves running an initial prompt on each chunk of data, that not only tries to complete a
+task but also gives a score for how certain it is in its answer. The responses are then
+ranked according to this score, and the highest score is returned.
+
+**Pros:** Similar pros as `MapReduceDocumentsChain`. Compared to `MapReduceDocumentsChain`, it requires fewer calls.
+
+**Cons:** Cannot combine information between documents. This means it is most useful when you expect there to be a single simple answer in a single document.

Deno offers built-in support for environment variables with `Deno.env`, and you can also use a `.env` file to store and access environment variables.\\n\\nUsing `Deno.env` is simple. It has getter and setter methods, so you can easily set and retrieve environment variables. For example, you can set the `FIREBASE_API_KEY` and `FIREBASE_AUTH_DOMAIN` environment variables like this:\\n\\n```ts\\nDeno.env.set(\"FIREBASE_API_KEY\", \"examplekey123\");\\nDeno.env.set(\"FIREBASE_AUTH_DOMAIN\", \"firebasedomain.com\");\\n\\nconsole.log(Deno.env.get(\"FIREBASE_API_KEY\")); // examplekey123\\nconsole.log(Deno.env.get(\"FIREBASE_AUTH_DOMAIN\")); // firebasedomain.com\\n```\\n\\nYou can also store environment variables in a `.env` file. This is a great'}, {'text': '\\n\\nEnvironment variables are a powerful tool for managing configuration settings in a program. They allow us to set values that can be used by the program, without having to hard-code them into the code. This makes it easier to change settings without having to modify the code.\\n\\nIn Deno, environment variables can be set in a few different ways. The most common way is to use the `VAR=value` syntax. This will set the environment variable `VAR` to the value `value`. This can be used to set any number of environment variables before running a command. For example, if we wanted to set the environment variable `VAR` to `hello` before running a Deno command, we could do so like this:\\n\\n```\\nVAR=hello deno run main.ts\\n```\\n\\nThis will set the environment variable `VAR` to `hello` before running the command. We can then access this variable in our code using the `Deno.env.get()` function. For example, if we ran the following command:\\n\\n```\\nVAR=hello && deno eval \"console.log(\\'Deno: \\' + Deno.env.get(\\'VAR'}, {'text': '\\n\\nEnvironment variables are a powerful tool for developers, allowing them to store and access data without having to hard-code it into their applications. In Deno, you can access environment variables using the `Deno.env.get()` function.\\n\\nFor example, if you wanted to access the `HOME` environment variable, you could do so like this:\\n\\n```js\\n// env.js\\nDeno.env.get(\"HOME\");\\n```\\n\\nWhen running this code, you\\'ll need to grant the Deno process access to environment variables. This can be done by passing the `--allow-env` flag to the `deno run` command. You can also specify which environment variables you want to grant access to, like this:\\n\\n```shell\\n# Allow access to only the HOME env var\\ndeno run --allow-env=HOME env.js\\n```\\n\\nIt\\'s important to note that environment variables are case insensitive on Windows, so Deno also matches them case insensitively (on Windows only).\\n\\nAnother thing to be aware of when using environment variables is subprocess permissions. Subprocesses are powerful and can access system resources regardless of the permissions you granted to the Den'}, {'text': '\\n\\nEnvironment variables are an important part of any programming language, and Deno is no exception. Deno is a secure JavaScript and TypeScript runtime built on the V8 JavaScript engine, and it recently added support for environment variables. This feature was added in Deno version 1.6.0, and it is now available for use in Deno applications.\\n\\nEnvironment variables are used to store information that can be used by programs. They are typically used to store configuration information, such as the location of a database or the name of a user. In Deno, environment variables are stored in the `Deno.env` object. This object is similar to the `process.env` object in Node.js, and it allows you to access and set environment variables.\\n\\nThe `Deno.env` object is a read-only object, meaning that you cannot directly modify the environment variables. Instead, you must use the `Deno.env.set()` function to set environment variables. This function takes two arguments: the name of the environment variable and the value to set it to. For example, if you wanted to set the `FOO` environment variable to `bar`, you would use the following code:\\n\\n```'}]\n"
