### Clippy | ||
|
||
The Clippy tool is a collection of lints to analyze your code so you can catch common mistakes and improve your Rust code. | ||
|
||
If you used the installation script for Rustlings, Clippy should be already installed. | ||
If not you can install it manually via `rustup component add clippy`. | ||
|
||
For more information about Clippy lints, please see [their documentation page](https://rust-lang.github.io/rust-clippy/master/). |
