 As an example you I have a folder in my `D:` drive that holds all my git repos, so I will setup `pygit` with the following command
 
-      python -m pygit --m D:\git -v 1 -t D:\

+If it happens that you clone more repos into your master directory, you may update the index by issuing the `update()`command inside a `python` shell.
