Fonts generated from icomoon.io. To add new icons, start by uploading the icomoon.json file to the icomoon.io web app, adding any new icons and then downloading the new font files. Add the downloaded icomoon.woff file to this directory, encode it in base64 (e.g., base64 icomoon.woff on many unix-like systems), and replace the old base64 string with the updated string in the _sass/fonts.scss file. Then modify _sass/icons.scss with the new icon css styles (e.g., add .icon-NAME:after for each new icon).
