I made a Micro.blog plug-in that loads Font Awesome in your blog, so it’s easier to add icons to blog posts or to use them in theme templates.
Update, 01 July 2022:
After I made the Font Awesome plug-in, I recorded a video about using it, including how Micro.blog themes work. There was a caching bug in the video, so wanted to re-record it after fixing it… But I don’t have time, so posting the video anyway! Enjoy, it’s on YouTube here.
