-Compiling Clippy from scratch can take almost a minute or more depending on your machine.
-However, since Rust 1.24.0 incremental compilation is enabled by default and compile times for small changes should be quick.

 [Llogiq's blog post on lints](https://llogiq.github.io/2015/06/04/workflows.html) is a nice primer
 to lint-writing, though it does get into advanced stuff. Most lints consist of an implementation of
 `LintPass` with one or more of its default methods overridden. See the existing lints for examples
 of this.
 
+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 guaratees][rfc_stability] and
+[lint categories][rfc_lint_cats] sections of the [Clippy 1.0 RFC][clippy_rfc] a

+### Running rustfmt
+
+[Rustfmt](https://github.com/rust-lang/rustfmt) is a tool for formatting Rust code according
+to style guidelines. The code has to be formatted by `rustfmt` before a PR will be merged.
+
+It can be installed via `rustup`:
+```bash
+rustup component add rustfmt-preview
+```
+
+Use `cargo fmt --all` to format the whole codebase.

 ### Testing manually
 
 Manually testing against an example file is useful if you have added some
 `println!`s and test suite output becomes unreadable.  To try Clippy with your
 local modifications, run `env CLIPPY_TESTS=true cargo run --bin clippy-driver -- -L ./target/debug input.rs`

+## Issue and PR triage
+
+Clippy is following the [Rust triage procedure][triage] for issues and pull
+requests.
+
+However, we are a smaller project with all contributors being volunteers
+currently. Between writing new lints, fixing issues, reviewing pull requests and
+responding to issues there may not always be enough time to stay on top of it
+all.
+
+Our highest priority is fixing [crashes][l-crash] and [bugs][l-bug]. We don't
+want Clippy to crash on your code and we want it to be as reliable as the
+suggestions from Rust compiler errors.
+
 ## Contributions
 
 Contributions to Clippy should be made in the form of GitHub pull requests. Each pull request will
 be reviewed by a core contributor (someone with permission to land patches) and either landed in the
 main tree or given feedback for changes that would be required.

The RFC's goal is to clarify policies around lint categorizations and the policy around which lints should be in the compiler and which lints should be in Clippy.
