+# Git pre-commit hooks
+
+To minimize review overhead OpenWhisk uses tools to enforce our coding standards. This is a set of git pre-commit hooks which will automatically check for formatting errors, so you don't need to wait for a CI build to fail to find those.
+
+## Scala
+
+Scala is formatted using [scalafmt](http://scalameta.org/scalafmt/). It's configuration can be found [here](../.scalafmt.conf). To automatically reformat **changed** Scala files upon commit, add the following to your `pre-commit` hook.
