Pushing to the repos

[Willow Liquorice]

Hello,

Given that I'm getting repository access soon, I'm getting my changes 
ready to be pushed.

I need to sign my commits, is that with the SSH key pair? Is the guide 
in the developer's manual in line with current practice? I've never used 
a VCS collaboratively before, and I'm a bit worried about screwing up my 
first major contribution.

Regards,
        Willow
