## Assumptions

1. **You're familiar with [Github](https://github.com) and the [pull request](https://help.github.com/en/github/collaborating-with-issues-and-pull-requests/about-pull-requests)
   workflow.**
2. **You've read the MeiliSearch [docs](https://docs.meilisearch.com).**
3. **You know about the [MeiliSearch community](https://docs.meilisearch.com/resources/contact.html).
   Please use this for help.**

## Your First Contribution

1. Ensure your change has an issue! Find an
   [existing issue](https://github.com/meilisearch/meilisearch/issues/) or [open a new issue](https://github.com/meilisearch/meilisearch/issues/new).
   * This is where you can get a feel if the change will be accepted or not.
2. Once approved, [fork the MeiliSearch repository](https://help.github.com/en/github/getting-started-with-github/fork-a-repo) in your own
   Github account.
3. [Create a new Git branch](https://help.github.com/en/github/collaborating-with-issues-and-pull-requests/creating-and-deleting-branches-within-your-repository)
4. Review the MeiliSearch [workflow](#workflow) and [development](#development).
5. Make your changes.
6. [Submit the branch as a pull request](https://help.github.com/en/github/collaborating-with-issues-and-pull-requests/creating-a-pull-request-from-a-fork) to the main MeiliSearch
   repo. A MeiliSearch team member should comment and/or review your pull request
   with a few days. Although, depending on the circumstances, it may take
   longer.

## Change Control

### Git Branches

_All_ changes must be made in a branch and submitted as [pull requests](#pull-requests).
MeiliSearch does not adopt any type of branch naming style, but please use something
descriptive of your changes.

### Git Commits

#### Style

Please ensure your commits are small and focused; they should tell a story of
your change. This helps reviewers to follow your changes, especially for more
complex changes.

Familiarise yourself with [How to Write a Git Commit Message](https://chris.beams.io/posts/git-commit/).

### Github Pull Requests

Once your changes are ready you must submit your branch as a pull request.

#### Reviews & Approvals

All pull requests must be reviewed and approved by at least one MeiliSearch team
member.

#### Merge Style

All pull requests are squashed and merged. We generally discourage large pull
requests that are over 300-500 lines of diff. If you would like to propose
a change that is larger we suggest coming onto our chat channel and
discuss it with one of our engineers. This way we can talk through the
solution and discuss if a change that large is even needed! This overall
will produce a quicker response to the change and likely produce code that
aligns better with our process.

## Development

### Setup

See the [MeiliSearch Docs](https://docs.meilisearch.com/guides/advanced_guides/installation.html) for how to set up a development environment.

### Benchmarking & Profiling

We do not yet do any benchmarking, nor have we formalised our profiling. If you'd like to work on this please get in touch!

## Humans

After making your change, you'll want to prepare it for MeiliSearch users (mostly humans). This usually entails updating documentation and announcing your feature.

### Documentation

Documentation is very important to MeiliSearch. All contributions that
alter user-facing behavior MUST include documentation changes. Please see
[GitHub.com/meilisearch/documentation](https://github.com/meilisearch/documentation) for more info.

### Changelog

Until we have guidelines in place, updating the [`Changelog`](/CHANGELOG.md) is solely the responsibility of MeiliSearch team members.
