Warning before git section in the deploy chapter

[asendecka]

On almost every workshop there is someone who does git init in the home directory and everything fails. I don't remember a workshop without that problem.

Idea: instead of having meta coaches fix that every time, maybe we can put a warning in git chapter. Add steps in the git tutorial to:

• do pwd to check if you're in the right directory
• do git status to see if the right files are being tracked
