+### Git hooks
+
+There is a pre-commit git hook stored in .git-hooks which can be installed by running `.git-hooks/install.bash`.
+
+The hooks:
+- Run Rubocop
+- Run tests
+- Run Brakeman
+
+### Brakeman
+
+If Brakeman issues are introduced, they should be immediately fixed or ignored with a note as to why it
+is not a real issue. To do so, run `bundle exec brakeman -I`.
