Like many of you, I bought a license for Font Awesome 5 during the Kickstarter years ago. Also like many of you, I could never have figure out how to use FA5 in my RW projects. Thanks to some support by Nick Cates on an unrelated question, I now know how! And you can, too!
Sign-in to your account, and create a Kit. FA will give you a
<script>. Copy that, and put it in the
Head Global Settings of your RW project.
Now, you can put in
<i class> tags of FA5 icons wherever you like.
RW won’t display the icons in edit mode. If I understand it correctly, FA changed the licensing with v5, which made it tough for Stacks to license it. However, in preview mode and when published, it shows up great.
