Installation with Cygwin

If you're comfortable with Cygwin, then use it to install git, ssh, wget and python. Install pip, and use pip to install git-review:

 $ wget http://peak.telecommunity.com/dist/ez_setup.py

 $ python ez_setup.py

 $ easy_install pip

 $ pip install git-review

Now, clone the repository and set up git-review:

 $ git clone ssh://<USERNAME>@gerrit.wikimedia.org:29418/mediawiki/core.git

 $ cd core; git review -s

You should be able to use git and git-review normally.
