Tutorial
Probably not an issue per se, but is there a manual for people who're not well-versed with git? 
- where does 'init-repo' push to? 
- where does 'push' go to? Is it using my git account if i'm logged in on www?
- how does the creating pngs for diffs work – how do I view them?
- troubleshooting

thanks for your time
