Enhance Readme

[milansismanovic]

Noobs question: Your Readme is great. Got everything working from there. Could you add a paragraph on how to add an additional git user?

I.e.
How to add an additional Git user:
Append the public key of the new git user to the ~/git-server/keys/id_rsa.pub and restart the git server

• From host: $ cat new_user_id_rsa.pub >>~/git-server/keys

Such a great way to setup a git. Hope you can help.

That's my question, too. Do I have to append all the public keys to the id_rsa.pub file in git-server/keys or is it possible to store them under different names (user1.pub, user2.pub, ...)
