 ## Prerequisites
 
-You'll need [git](http://git-scm.com/), [Python 2.7](https://www.python.org/download/releases/2.7.8/), and setuptools before you can proceed. To install setuptools, download [ez_setup.py](https://bootstrap.pypa.io/ez_setup.py) into a directory with no Unicode characters in the path, and run it using `python ez_setup.py`. Then follow the instructions at [buildbot-slave](http://trac.buildbot.net/wiki/DownloadInstall).
