+You can set the `GIT_SHOW_UNTRACKED_FILES` variable to `no` or `normal` to speed things up if you have lots of
+untracked files in your repository. This can be the case for build systems that put their build artifacts in
+the subdirectory structure of the git repository.
+
 - `cd` to a git repository and test it!
