PIP is the recommended method for installing Python packages. Each time I need to install it I end up doing a quick search as it’s not something I do often enough to remember the process. So, to save my future self 30 seconds, here is the process.
The official resource is the [PIP Installer documentation](http://www.pip- installer.org/en/latest/installing.html).
Linux / CentOS 6.5
wget https://raw.github.com/pypa/pip/master/contrib/get-pip.py python get-pip.py
