+Should you add a lint, try it on clippy itself using `util/dogfood.sh`. You may find that clippy
+contains some questionable code itself! Also before making a pull request, please run
+`util/update_lints.py`, which will update `lib.rs` and `README.md` with the lint declarations. Our
+travis build actually checks for this.
+
+Also please document your lint with a doc comment akin to the following:
+```
+/// **What it does:** Describe what the lint matches.
+///
+/// **Why is this bad?** Write the reason for linting the code.
+///
+/// **Known problems:** Hopefully none.
+///
+/// **Example:** Insert a short example if you have one
+```
+
+Our `util/update_wiki.py` script can then add your lint docs to the wiki.
