title: Place git repository on external hard drive
body: <p>I am using XCODE, and have recently decided to try using git (I am a lone app developer, so never really needed to use it). Because it used to take up a lot of storage space when I tried it previously, all of my current projects with git are stored on an external hard drive. I was wondering, however, whether it is possible to keep a development branch of a project on the hard drive of the mac, while keeping the main branch on the external hard drive. That way, I can merge the stable branches every few days to the external hard drive, and keep the development copy on my macbook to remove the need to carry my external hard drive with me everywhere I go. Is this possible? Any suggestions for a newbie on git?</p>
