# Clippy Development

Hello fellow Rustacean! If you made it here, you're probably interested in making Clippy better by contributing to it. In that case, welcome to the project!

Note: If you're just interested in using Clippy, there's nothing to see from this point onward and you should return to one of the earlier chapters.

## Getting started

If this is your first time contributing to Clippy, you should first read the Basics docs. This will explain the basics on how to get the source code and how to compile and test the code.

## Writing code

If you have done the basic setup, it's time to start hacking.

The Adding lints chapter is a walk through on how to add a new lint to Clippy. This is also interesting if you just want to fix a lint, because it also covers how to test lints and gives an overview of the bigger picture.

If you want to add a new lint or change existing ones apart from bugfixing, it's also a good idea to give the stability guarantees and lint categories sections of the Clippy 1.0 RFC a quick read. The lint categories are also described earlier in this book.

Note: Some higher level things about contributing to Clippy are still covered in the CONTRIBUTING.md document. Some of those will be moved to the book over time, like:

• Finding something to fix
• IDE setup
• High level overview on how Clippy works
• Triage procedure
• Bors and Homu
