First, clone a remote Git repository and cd into it:  
$ git clone git://example.com/myproject 
$ cd myproject 

Next, look at the local branches in your repository:  
$ git branch 
* master 

But there are other branches hiding in your repository! You can see these using the -a flag:  
$ git branch -a
