getting started with git in Clion -- not seeing unversioned files in change list

hello, I'm new to Clion and now trying to learn to use the git support.   I have an existing project directory.   I've used Clion to create a local git repository.    That did enable the git related menu items.   Following the Clion documentation I next selected the commit view.  It shows one change list called simple ‘Changes’ the is empty.   I was expecting, as per documentation, an unversioned files list from which I could select files to add to git, but no such luck.

Suggestions???

Thanks, John
