Another milestone accomplished: I now have a basic custom theme installed on my Micro.blog test website. It’s not a plugin per se; it’s a custom theme stored on my GitHub account that Micro.blog fetches. I don’t yet know how to turn it into a plugin with version numbering and all that, but I might not need that after all. I just wish Micro.blog would update automatically whenever I push a new change to my repo, like Vercel does.
