The Github has an installer you can just run and install.
Hard way:

The Gcode for thestart script does not have M104 (Set Extruder Temp) so that cura can generate those for you. If the M104 was in the start script then you would have do disable the other extruder like Egurs profile or have whole different profiles for each side like Lyl3s profile. So you need to make sure that you have a skirt around your print because this profile does not have any purge nozzle scripts in the starting Gcode.
This is set to reprap for better use with Octoprint.
