Install Git for Windows from http://code.google.com/p/msysgit/. Note you just want to grab Git, not msysGit.
 
 When you clone a repository, you will want to use the following syntax:
-   git clone ssh://tannenba@chevre.cs.wisc.edu:/p/condor/repository/CONDOR_SRC.git
+   git clone ssh://tannenba@chevre.cs.wisc.edu/p/condor/repository/CONDOR_SRC.git
 
 
 Since Git includes an ssh.exe in its bin/ directory, you should be good to go -- but you will have to enter your ssh password whenever you git clone/pull/push/fetch, or otherwise do comparisons against the origin.
