To collaborate in a distributed development process you'll need to push code to remotely accessible repositories. This is somewhat of a follow-up to the previous article setting up a new rails app with git. It's good to know how this stuff works, but this is definitely the hard way. For no fuss git repository setup (especially if you want to collaborate with others) Check out GitHub.For the impatient Set up the new bare Repo On the server: $ ssh myserver.comWelcome to myserver.com!$ mkdir /var/g
