This is the git flow tutorial (ask Ben to install git flow for you on your machine).
2) Get Daniel to invite you to the github project ,
3) create and change to a folder of your choice
4) "git flow init" and enter-enter-enter-enter-enter
5) "git clone <address of git-hub repository provided by Daniel>"
You can then start new features like Daniel showed yesterday, as described in the tutorial, etc. (e.g., "git flow feature start <feature-name>")
