+2.  Edit `ligatures.py` to disable any ligatures you don't want, and/or enable any (non-ligature) characters you want from Fira Code in addition to the ligatures.
 3.  Run the script: `$ fontforge -lang=py ligaturize.py <INPUT> <OUTPUT>`, e.g. `$ fontforge -lang=py ligaturize.py input-fonts/Cousine-Regular.ttf output-fonts/CousineLigaturized-Regular.ttf`
 
 The font family and weight for the output font (as recorded in the file) will be automatically set based on the name; if the output is `CousineLigaturized-Regular.ttf`, the font family will be `CousineLigaturized` and the font weight will be `Regular`. If no weight is specified, `Regular` is the default.
