Actually, let's rework step 1 better as my comment is really not a step.
Here's what I think should be helpful.
1) Release has to be done from branch "develop". Make sure you have a working and up-to-date develop's branch (your local branch must not be behind any remote-server's commits)
  - if you have no local copy of fas's repository
   git clone [...]
  - if you have a local copy of fas's repository already
   git pull develop  
/!\ WARNING: this will overwrite any uncommited changes.
