+Thank you for making Clippy better!
+
+We're collecting our changelog from pull request descriptions.
+If your PR only includes internal changes, you can just write
+`changelog: none`. Otherwise, please write a short comment
+explaining your change.
+
+It's also helpful for us that the lint name is put within backticks (`` ` ` ``),
+and then encapsulated by square brackets (`[]`), for example:
+```
+changelog: [`lint_name`]: your change
+```
+
+If your PR fixes an issue, you can add `fixes #issue_number` into this
+PR description. This way the issue will be automatically closed when
+your PR is merged.
+
+If you added a new lint, here's a checklist for things that will be
+checked during review or continuous integration.
+
+- \[ ] Followed [lint naming conventions][lint_naming]
+- \[ ] Added passing UI tests (including committed `.stderr` file)
+- \[ ] `cargo test` passes locally
+- \[ ] Executed `cargo dev update_lints`
+- \[ ] Added lint documentation
+- \[ ] Run `cargo dev fmt`
+
+[lint_naming]: https://rust-lang.github.io/rfcs/0344-conventions-galore.html#lints
+
+Note that you can skip the above if you are just opening a WIP PR in
+order to get feedback.
+
+Delete this line and everything above before opening your PR.
