formBuilder uses an icon font generated with Fontello. Fontello makes it easy for developers to collaborate by providing an API we can incorporate with our normal build processes.
To edit the current icon font, open terminal and run:
yarn font edit
This will open and create a new session on fontello.com where you can choose new icons or upload your own.
When finished, click the Save Session button and return to the terminal and type:
yarn font save
