We are a team of three, all working on our local machines on the same internal network. We will all be working on websites in local working copies of the same Git repo hosted on Github. We have an internal staging machine here (dev.internal), and I am looking for a way for us to be able to push to this machine. At each milestone in the development cycle. In essence, all I really want us to be able to do is add the dev.internal machine as a remote, and push to this whenever we are ready. Could somebody please point me in the right direction to get this set up?
