+## Components
+
+If you are going to install `clippy`, `rustfmt` or any other [rustup component](https://rust-lang.github.io/rustup-components-history/),
+it might not be available in latest `nightly` build;
+check out the [`actions-rs/components-nightly`](https://github.com/actions-rs/components-nightly) Action,
+which makes this process much easier.

 ## Notes
 
-As `rustup` is not installed by default for macOS and Windows images at the moment (2019-09-13),
-this Action will try its best to install it before any other operations.
