-**🧐 Evaluation:**
-
-[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.

-**Weaviate in a nutshell:**
-- Weaviate is an open-source ​database of the type ​vector search engine.
-- Weaviate allows you to store JSON documents in a class property-like fashion while attaching machine learning vectors to these documents to represent them in vector space.
-- Weaviate can be used stand-alone (aka bring your vectors) or with a variety of modules that can do the vectorization for you and extend the core capabilities.
-- Weaviate has a GraphQL-API to access your data easily.
-- We aim to bring your vector search set up to production to query in mere milliseconds (check our [open source benchmarks](https://weaviate.io/developers/weaviate/current/benchmarks/) to see if Weaviate fits your use case).
-- Get to know Weaviate in the [basics getting started guide](https://weaviate.io/developers/weaviate/current/core-knowledge/basics.html) in under five minutes.

-**Weaviate in detail:**
-
-Weaviate is a low-latency vector search engine with out-of-the-box support for different media types (text, images, etc.). It offers Semantic Search, Question-Answer Extraction, Classification, Customizable Models (PyTorch/TensorFlow/Keras), etc. Built from scratch in Go, Weaviate stores both objects and vectors, allowing for combining vector search with structured filtering and the fault tolerance of a cloud-native database. It is all accessible through GraphQL, REST, and various client-side programming languages.

+- 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.rst>`_ documentation.
+- Agents: An agent uses an LLMChain to determine which tools to use. For a list of all available agent types, see `here <../explanation/agents.md>`_.

+Chains
+======
+
+The examples here are all end-to-end chains for specific applications.
+A chain is made up of links, which can be either primitives or other chains.
+
+The following primitives exist as options to use for links:
+
+#. `LLM: <../modules/llms.rst>`_ A language model takes text as input and outputs text.
+#. `PromptTemplate: <../modules/prompt.rst>`_ A prompt template takes arbitrary string inputs and returns a final formatted string.
+#. `TextSplitter: <../modules/text_splitter.rst>`_ A text splitter takes a longer document and splits it into smaller chunks.
+#. `Python REPL: <../modules/python.rst>`_ A Python REPL takes a string representing a Python command to run, runs that command, and then returns anything that was printed during that run.
+#. `SQL Database: <../modules/sql_database.rst>`_ A SQL database takes a string representing a SQL command as input and executes that command against the database. If any rows are returned, then those are cast to a string and returned.
+#. `Search: <../modules/serpapi.rst>`_ A search object takes a string as input and executes that against a search object, returning any results.
+#. `Docstore: <../modules/docstore.rst>`_ A docstore object can be used to lookup a document in a database by exact match.
+#. `Vectorstore: <../modules/vectorstore.rst>`_ A vectorstore object uses embeddings stored in a vector database to take in an input string and return documents similar to that string.
+
+With these primitives in mind, the following chains exist:
+
+**LLMChain**
+
+- **Links Used**: PromptTemplate, LLM
+- **Notes**: This chain is the simplest chain, and is widely used by almost every other chain. This chain takes arbitrary user input, creates a prompt with it from the PromptTemplate, passes that to the LLM, and then returns the output of the LLM as the final output.
+- `Example Notebook <chains/llm_chain.ipynb>`_
+
+**LLMMath**
+
+- **Links Used**: Python REPL, LLMChain
+- **Notes**: This chain takes user input (a math question), uses an LLMChain to convert it to python code snippet to run in the Python REPL, and then returns that as the result.

+**PAL**
+
+- **Links Used**: Python REPL, LLMChain
+- **Notes**: This chain takes user input (a reasoning question), uses an LLMChain to convert it to python code snippet to run in the Python REPL, and then returns that as the result.

+- `Example Notebook <chains/pal.ipynb>`_
+
+**Recursive Summarization**
+
+- **Links Used**: TextSplitter, LLMChain
+- **Notes**: This chain splits a document into chunks, runs a first LLMChain over each chunk to summarize it, and then runs a second LLMChain over those results to get a summary of the summaries.
+- `Example Notebook <chains/map_reduce.ipynb>`_
+
+**SQLDatabase Chain**
+
+- **Links Used**: SQLDatabase, LLMChain
+- **Notes**: This chain takes user input (a question), uses a first LLM chain to construct a SQL query to run against the SQL database, and then uses another LLMChain to take the results of that query and use it to answer the original question.
+- `Example Notebook <chains/sqlite.ipynb>`_
+
+
+**Vector Database Question-Answering**
+
+- **Links Used**: Vectorstore, LLMChain
+- **Notes**: This chain takes user input (a question), uses the Vectorstore and semantic search to find relevant documents, and then passes the documents plus the original question to another LLM to generate a final answer.
+- `Example Notebook <chains/vector_db_qa.ipynb>`_
+
+**Vector Database Question-Answering With Sources**
+
+- **Links Used**: Vectorstore, LLMChain
+- **Notes**: This chain takes user input (a question), uses the Vectorstore and semantic search to find relevant documents, and then passes the documents plus the original question to another LLM to generate a final answer with sources.
+- `Example Notebook <chains/vector_db_qa_with_sources.ipynb>`_
+
+**Question-Answering With Sources**
+
+- **Links Used**: LLMChain
+- **Notes**: These types of chains take a question and multiple documents as input, and return an answer plus sources for where that answer came from. There are multiple underlying types of chains to do this, for more information see TODO.

The speaker also announces the closing of American airspace to Russian flights, further isolating Russia and adding an additional squeeze on their economy. The Russian stock market has lost 40% of its value and trading remains suspended. Together with our allies, the United States is providing military, economic, and humanitarian assistance to Ukraine, and has mobilized forces to protect NATO countries.

The speaker emphasizes that the United States and its allies will defend every inch of NATO territory and that Putin will pay a high price for his aggression. The speaker also acknowledges the hardships faced by the American people due to the pandemic and the American Rescue Plan, which has provided immediate economic relief for tens of millions of Americans, helped put food on their table, keep a roof over their heads, and cut the cost of health insurance.

 ## Augmenting
 So you've fetched your relevant data - now what? How do you pass them to the language model in a format it can understand?
-For a detailed overview of the different ways of doing so, and the tradeoffs between them, please see 
-[this documentation](../modules/chains/combine_docs.md)
+There are a few different methods, or chains, for doing so. LangChain supports three 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 `RefineDocumentsChain`.
+
+**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.
 
 ## Use Cases
 LangChain supports the above three methods of augmenting LLMs with external data.

+# 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.
+
+## PromptTemplates
+PromptTemplates 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.
+
+For a more detailed explanation of how LangChain approaches prompts and prompt templates, see [here](/examples/prompts/prompt_management).
+
+## 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.
+
+## Agents
+As opposed to a chain, whether the steps to be taken are known ahead of time, agents
+use an LLM to determine which tools to call and in what order.
+
+## Memory
+By default, Chains and Agents are stateless, meaning that they treat each incoming query independently.
+In some applications (chatbots being a GREAT example) it is highly important to remember previous interactions,
+both at a short term but also at a long term level. The concept of "Memory" exists to do exactly that.

+# 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).
+
+```python
+import os
+os.environ["OPENAI_API_KEY"] = "..."
+```

-# 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 for 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).
-
-
-```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.")
-```
-
-```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:  Hello! How are you today?
-Human: I'm doing well! Just having a conversation with an AI.
-AI:
-
-> Finished chain.
-" That's great! What would you like to talk about?"

-Getting Started
-----------------
+There are four main areas that LangChain is designed to help with.
+These are, in increasing order of complexity:
 
-Checkout the below guide for a walkthrough of how to get started using LangChain to create an Language Model application.
+1. LLM and Prompts
+2. Chains
+3. Agents
+4. Memory
+
+Let's go through these categories and for each one identify key concepts (to clarify terminology) as well as the problems in this area LangChain helps solve.
+
+**🦜 LLMs and Prompts**
+
+Calling out to an LLM once is pretty easy, with most of them being behind well documented APIs.
+However, there are still some challenges going from that to an application running in production that LangChain attempts to address.
+
+*Key Concepts*
+
+- LLM: A large language model, in particular a text-to-text model.
+- Prompt: The input to a language model. Typically this is not simply a hardcoded string but rather a combination of a template, some examples, and user input.
+- Prompt Template: An object responsible for constructing the final prompt to pass to a LLM.
+
+*Problems Solved*
+
+- Switching costs: by exposing a standard interface for all the top LLM providers, LangChain makes it easy to switch from one provider to another, whether it be for production use cases or just for testing stuff out.
+- Prompt management: managing your prompts is easy when you only have one simple one, but can get tricky when you have a bunch or when they start to get more complex. LangChain provides a standard way for storing, constructing, and referencing prompts.
+- Prompt optimization: despite the underlying models getting better and better, there is still currently a need for carefully constructing prompts.
+
+**🔗️ Chains**
+
+Using an LLM in isolation is fine for some simple applications, but many more complex ones require chaining LLMs - either with eachother or with other experts.
+LangChain provides several parts to help with that.
+
+*Key Concepts*
+
+- Tools: APIs designed for assisting with a particular use case (search, databases, Python REPL, etc). Prompt templates, LLMs, and chains can also be considered tools.
+- Chains: A combination of multiple tools in a deterministic manner.
+
+*Problems Solved*
+
+- Standard interface for working with Chains
+- Easy way to construct chains of LLMs
+- Lots of integrations with other tools that you may want to use in conjunction with LLMs
+- End-to-end chains for common workflows (database question/answer, recursive summarization, etc)
+
+**🤖 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.
+Depending on the user input, the agent can then decide which, if any, of these tools to call.
+

+**🧠 Memory**
+
+By default, Chains and Agents are stateless, meaning that they treat each incoming query independently.
+In some applications (chatbots being a GREAT example) it is highly important to remember previous interactions,
+both at a short term but also at a long term level. The concept of "Memory" exists to do exactly that.
+
+*Key Concepts*
+
+- Memory: A class that can be added to an Agent or Chain to (1) pull in memory variables before calling that chain/agent, and (2) create new memories after the chain/agent finishes.
+- Memory Variables: Variables returned from a Memory class, to be passed into the chain/agent along with the user input.
+
+*Problems Solved*
+
+- Standard memory interfaces
+- A collection of common memory implementations to choose from
+- Common chains/agents that use memory (e.g. chatbots)

-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.
-
-- `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.
+Goes over a simple walk through and tutorial for getting started setting up a simple chain that generates a company name based on what the company makes.
+Covers installation, environment set up, calling LLMs, and using prompts.
+Start here if you haven't used LangChain before.

-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 <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.
+More elaborate examples and walk-throughs of particular
+integrations and use cases. This is the place to look if you have questions
+about how to integrate certain pieces, or if you want to find examples of
+common tasks or cool demos.

-Some applications will require not just a predetermined chain of calls to LLMs/other tools,

-In these types of chains, there is a “agent” which has access to a suite of tools.
-Depending on the user input, the agent can then decide which, if any, of these tools to call.

-How-To Guides
-=============
-
-The first category of how-to guides here cover specific parts of working with agents.
-
-`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.
-
-
-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 <../explanation/tools.html>`_
-- Agents: An agent uses an LLMChain to determine which tools to use. For a list of all available agent types, see `here <../explanation/agents.html>`_.

-# Key Concepts
-
-## Agents
-Agents use an LLM to determine which actions to take and in what order.
-For more detailed information on agents, and different types of agents in LangChain, see [this documentation](agents.md).
-
-## 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.

-# 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:
-- Tool Name: The name the LLM refers to the tool by.
-- Tool Description: The description of the tool that is passed to the LLM.
-- Notes: Notes about the tool that are NOT passed to the LLM.
-- Requires LLM: Whether this tool requires an LLM to be initialized.
-- (Optional) Extra Parameters: What extra parameters are required to initialize this tool.
-
-## List of Tools
-
-**python_repl**

-- Tool Name: Search
-- Tool Description: A search engine. Useful for when you need to answer questions about current events. Input should be a search query.
-- Notes: Calls the Serp API and then parses results.
-- Requires LLM: No
-
-**requests**
-- Tool Name: Requests
-- Tool Description: A portal to the internet. Use this when you need to get specific content from a site. Input should be a specific url, and the output will be all the text on that page.
-- Notes: Uses the Python requests module.
-- Requires LLM: No
-
-**terminal**
-- Tool Name: Terminal
-- Tool Description: Executes commands in a terminal. Input should be valid commands, and the output will be any output from running that command.
-- Notes: Executes commands with subprocess.

+=======================
 
-Using an LLM in isolation is fine for some simple applications,
-but many more complex ones require chaining LLMs - either with eachother or with other experts.
-LangChain provides a standard interface for Chains, as well as some common implementations of chains for easy use.
