Thanks to Robb Knight’s explanation of how Author Tags work on Mastodon, I was able to activate them on my Micro.blog website.
Prerequisite: I’m using the Sumo theme, which has full support for Microhooks. Please check if your theme supports them before going ahead.
The process is very simple from the Micro.blog web dashboard:
go to Design → Open Theme → New Template
Give the template this location and name:
layouts/partials/microhook-head.html
insert this code using your fediverse handle name instead of mine:
<meta property="fediverse:creator" content="@prealpinux@mastodon.uno" />
Well done, you’re ready to go!
Disclaimer: I tried to use multiple author tags, but there seems to be no support for them at the moment.
