+# Hooks
+
+The Hooks folder includes a standard pre-commit and pre-receive that will be enforced across repos. These pre-commit and pre-receive will enforce the contents of `Hooks/scripts.d`. This allows us to enforce standards of quality across the ecosystem.
+
+Notably, each repo that subscribes to this enforcement can also commit their own standards in addition to global standards. Python tests should go in a folder called `tests/` and scripts in a folder called `precommit-hooks/`. These will be run in addition to the global hooks.
