## 🗺️ Guidelines
### 👩💻 Contributing Code
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
Please follow the checked-in pull request template when opening pull requests. Note related issues and tag relevant
maintainers.
Pull requests cannot land without passing the formatting, linting and testing checks first. See
[Common Tasks](#-common-tasks) for how to run these checks locally.
It's essential that we maintain great documentation and testing. If you:
- Fix a bug
- Add a relevant unit or integration test when possible. These live in `tests/unit_tests` and `tests/integration_tests`.
- Make an improvement
- Update any affected example notebooks and documentation. These lives in `docs`.
- Update unit and integration tests when relevant.
- Add a feature
- Add a demo notebook in `docs/modules`.
- Add unit and integration tests.
We're a small, building-oriented team. If there's something you'd like to add or change, opening a pull request is the
best way to get our attention.

There is a taxonomy of labels to help with sorting and discovery of issues of interest. Please use these to help
organize issues.
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.
If you are adding an issue, please try to keep it focused on a single, modular bug/improvement/feature.
If two issues are related, or blocking, please link them rather than combining them.
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with the rapid rate of develop in this field some may get out of date.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.
Our goal is to have the simplest developer setup possible. Should you experience any difficulty getting setup, 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 by
a developer and published to [PyPI](https://pypi.org/project/langchain/).
