1. PLEASE READ THE FOLLOWING INSTRUCTIONS -
Make sure (if you don’t already have them on your system), to install the
bundled fonts BEFORE you open the Sketch file.
If you don’t install the fonts, and decide to open the Sketch file, you may
experience layout issues with your file, as a substitute font will be used.
