If you want to get source code from GitHub it’s easy enough to click ‘Download’ if you just want an archive. However if you’re on GitHub you might want to use the proper git client.
Get git if you haven’t already:
Once that’s installed just run the following from a command line:
git clone git://github.com/username/project.git
To get the connect-auth source tree use:
git clone git://github.com/ciaranj/connect-auth.git
Enjoy your new source.
