In case you’d like to add custom icons to the theme and use them on your site, please, follow these steps.
1. Create the icons in svg format (draw them or upload from any resource).
2. Convert the icons to the icon font. You can use any convenient converter (e.g. IcoMoonApp). You can skip this step in case you already have the icon font.
3. Navigate to the admin panel > Brainstorm > Icon Manager and upload new icons.
