 ## Lint name
 
-A good lint name is important, it is usually given by the issue you're fixing (in the **Lint name** field). If you're unsure if the name you chose fits the lint, you can check the [lint naming guidelines][lint_naming]. Don't worry, if the lint name doesn't fit, a Clippy team member will alert you in the PR process.
