Redmine

Hello all, I've installed 3.0.3 on a cenOS6 virtual server. All works there as expected. I have two issues..

I followed this guide for installation into redmine http://www.redmine.org/projects/redmine/wiki/HowTo_configure_Redmine_for_advanced_git_integration

I got through most steps.. but I start getting confused when it talks about integrating with apache. I know GIT is installed because I can see it in settings so I've at least done that part right. I'm also very confident that grack is installed per the instructions minus a few changes to directory paths.

1) I don't know how to use GIT or how to setup a repository manually. Some of you are probably asking why I went with GIT if I don't know how to use it. I was overruled in a collective effort. I am very familiar with SVN and even had it automated to create the repo via crontab automatically whenever a project was created. Can someone steer me in the right direction on figuring out (via a link or otherwise) how to setup a git repo in redmine and use it?

2) How can I automate the crontab much like I did with SVN prior to automate a GIT repo when a project is created?

Help?

Thanks in advance.
