+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our
+community a harassment-free experience for everyone, regardless of age, body
+size, visible or invisible disability, ethnicity, sex characteristics, gender
+identity and expression, level of experience, education, socio-economic status,
+nationality, personal appearance, race, caste, color, religion, or sexual
+identity and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming,
+diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our
+community include:
+
+* Demonstrating empathy and kindness toward other people
+* Being respectful of differing opinions, viewpoints, and experiences
+* Giving and gracefully accepting constructive feedback
+* Accepting responsibility and apologizing to those affected by our mistakes,
+  and learning from the experience
+* Focusing on what is best not just for us as individuals, but for the overall
+  community
+
+Examples of unacceptable behavior include:
+
+* The use of sexualized language or imagery, and sexual attention or advances of
+  any kind
+* Trolling, insulting or derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or email address,
+  without their explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of
+acceptable behavior and will take appropriate and fair corrective action in
+response to any behavior that they deem inappropriate, threatening, offensive,
+or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject
+comments, commits, code, wiki edits, issues, and other contributions that are
+not aligned to this Code of Conduct, and will communicate reasons for moderation
+decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public spaces.
+Examples of representing our community include using an official e-mail address,
+posting via an official social media account, or acting as an appointed
+representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported to the community leaders responsible for enforcement at
+conduct@langchain.dev.
+All complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the
+reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining
+the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed
+unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing
+clarity around the nature of the violation and an explanation of why the
+behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series of
+actions.
+
+**Consequence**: A warning with consequences for continued behavior. No
+interaction with the people involved, including unsolicited interaction with
+those enforcing the Code of Conduct, for a specified period of time. This
+includes avoiding interactions in community spaces as well as external channels
+like social media. Violating these terms may lead to a temporary or permanent
+ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including
+sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public
+communication with the community for a specified period of time. No public or
+private interaction with the people involved, including unsolicited interaction
+with those enforcing the Code of Conduct, is allowed during this period.
+Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community
+standards, including sustained inappropriate behavior, harassment of an
+individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within the
+community.
+
+## Attribution

+## 📕 Releases & Versioning
 
 As of now, LangChain has an ad hoc release process: releases are cut with high frequency by
-a developer and published to [PyPI](https://pypi.org/project/langchain/).
+a maintainer and published to [PyPI](https://pypi.org/). 
+The different packages are versioned slightly differently.
 
-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).
+### `langchain-core`
 
-### 🌟 Recognition
+`langchain-core` is currently on version `0.1.x`. 
+
+As `langchain-core` contains the base abstractions and runtime for the whole LangChain ecosystem, we will communicate any breaking changes with advance notice and version bumps. The exception for this is anything in `langchain_core.beta`. The reason for `langchain_core.beta` is that given the rate of change of the field, being able to move quickly is still a priority, and this module is our attempt to do so.
+
+Minor version increases will occur for:
+
+- Breaking changes for any public interfaces NOT in `langchain_core.beta`
+
+Patch version increases will occur for:
+
+- Bug fixes
+- New features
+- Any changes to private interfaces
+- Any changes to `langchain_core.beta`
+
+### `langchain`
+
+`langchain` is currently on version `0.0.x`
+
+All changes will be accompanied by a patch version increase. Any changes to public interfaces are nearly always done in a backwards compatible way and will be communicated ahead of time when they are not backwards compatible.
+
+We are targeting January 2024 for a release of `langchain` v0.1, at which point `langchain` will adopt the same versioning policy as `langchain-core`.
+
+### `langchain-community`
+
+`langchain-community` is currently on version `0.0.x`
+
+All changes will be accompanied by a patch version increase.
+
+### `langchain-experimental`

+## Zapier Natural Language Actions API
+\
+Full docs here: https://nla.zapier.com/start/
+
+**Zapier Natural Language Actions** gives you access to the 5k+ apps, 20k+ actions
+on Zapier's platform through a natural language API interface.
+
+NLA supports apps like Gmail, Salesforce, Trello, Slack, Asana, HubSpot, Google Sheets,
+Microsoft Teams, and thousands more apps: https://zapier.com/apps
+
+Zapier NLA handles ALL the underlying API auth and translation from
+natural language --> underlying API call --> return simplified output for LLMs
+The key idea is you, or your users, expose a set of actions via an oauth-like setup
+window, which you can then query and execute via a REST API.
+
+NLA offers both API Key and OAuth for signing NLA API requests.
+
+1. Server-side (API Key): for quickly getting started, testing, and production scenarios
+    where LangChain will only use actions exposed in the developer's Zapier account
+    (and will use the developer's connected accounts on Zapier.com)
+
+2. User-facing (Oauth): for production scenarios where you are deploying an end-user
+    facing application and LangChain needs access to end-user's exposed actions and
+    connected accounts on Zapier.com
+
+This quick start will focus on the server-side use case for brevity.
+Review [full docs](https://nla.zapier.com/start/) for user-facing oauth developer
+support.
+
+Typically, you'd use SequentialChain, here's a basic example:
+
+    1. Use NLA to find an email in Gmail
+    2. Use LLMChain to generate a draft reply to (1)
+    3. Use NLA to send the draft reply (2) to someone in Slack via direct message
+
+In code, below:
+
+```python
+
+import os
+
+# get from https://platform.openai.com/
+os.environ["OPENAI_API_KEY"] = os.environ.get("OPENAI_API_KEY", "")
+
+# get from https://nla.zapier.com/docs/authentication/
+os.environ["ZAPIER_NLA_API_KEY"] = os.environ.get("ZAPIER_NLA_API_KEY", "")
+
+from langchain_community.agent_toolkits import ZapierToolkit
+from langchain_community.utilities.zapier import ZapierNLAWrapper
+
+## step 0. expose gmail 'find email' and slack 'send channel message' actions
+
+# first go here, log in, expose (enable) the two actions:
+#    https://nla.zapier.com/demo/start
+#    -- for this example, can leave all fields "Have AI guess"
+# in an oauth scenario, you'd get your own <provider> id (instead of 'demo')
+# which you route your users through first
+
+zapier = ZapierNLAWrapper()
+## To leverage OAuth you may pass the value `nla_oauth_access_token` to
+## the ZapierNLAWrapper. If you do this there is no need to initialize
+## the ZAPIER_NLA_API_KEY env variable
+# zapier = ZapierNLAWrapper(zapier_nla_oauth_access_token="TOKEN_HERE")

+I also had a sync with the design team to ensure the final touchups are in 
+line with the brand guidelines. Today, I'll start integrating the frontend with

+ the backend work for user data retrieval yesterday. 
+ The endpoints are mostly set up, but I need to do a bit more testing today. 
+ I'll finalize the API documentation by noon, so that should unblock Alex. 
+ After that, I’ll be working on optimizing the database queries 
+ for faster data fetching. No other blockers on my end.
+Sam: Great, thanks Rhea. Do reach out if you need any testing assistance
+ or if there are any hitches with the database. 
+ Now, my update: Yesterday, I coordinated with the client to get clarity 
+ on some feature requirements. Today, I'll be updating our project roadmap 
+ and timelines based on their feedback. Additionally, I'll be sitting with 
+ the QA team in the afternoon for preliminary testing. 
+ Blocker: I might need both of you to be available for a quick call 
+ in case the client wants to discuss the changes live.
+Alex: Sounds good, Sam. Just let us know a little in advance for the call.
+Rhea: Agreed. We can make time for that.
