Fenix is built on node-webkit, which is capable of running applications on Windows, Mac OSX, and Linux. With a little work, it's possible to run Fenix on any of the operating systems supported by node-webkit.

First, you'll need to install node-webkit. Instructions for this are available on the node-webkit download page. Node-webkit must be in your system path to work properly.

Once node-webkit is installed, you'll need the source code for Fenix. This can be obtained by cloning the git repository into a directory of your choosing:

git clone https://github.com/coreybutler/fenix.git

This will create a directory called fenix. Navigate into it (cd fenix) and type nw src to launch Fenix.
