 Lints are divided into categories, each with a default [lint level](https://doc.rust-lang.org/rustc/lints/levels.html).
 You can choose how much Clippy is supposed to ~~annoy~~ help you by changing the lint level by category.

+Clippy can also be used in projects that do not use cargo. To do so, you will need to replace
+your `rustc` compilation commands with `clippy-driver`. For example, if your project runs:
 
 ```terminal
-cargo run --bin cargo-clippy --manifest-path=path_to_clippys_Cargo.toml
+rustc --edition 2018 -Cpanic=abort foo.rs
 ```
 
-*Note:* Be sure that Clippy was compiled with the same version of rustc that cargo invokes here!
+Then, to enable Clippy, you will need to call:
+
+```terminal
+clippy-driver --edition 2018 -Cpanic=abort foo.rs
+```
+
+Note that `rustc` will still run, i.e. it will still emit the output files it normally does.
