 [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
+quick read.

-We are currently in the process of discussing Clippy 1.0 via the RFC process in https://github.com/rust-lang/rfcs/pull/2476 . 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. Please leave your thoughts on the RFC PR.
