Allow Git command line access under chrooted bash?

I'd like to allow some users git command-line use from a chrooted bash session so that they can link to and manage their Plesk git repo (or remote to any repo, if desired). I have to questions:

1. How do I do this (correctly)? I saw this article re: adding SSH, and I assume that I would do similarly.
2. Are there security implications that I'm not thinking of from allowing git binary access in chrooted bash?

Thank you,
Daniel
