@petar The easiest way to do this without changing any theme code is by adding the Mastodon verification link to your site’s custom footer:

> Design > Open Theme: “Your theme” > Custom Footer

Then in the custom footer, paste the link back to your Mastodon instance:

<a href="link%20to%20mastodon%20user" rel="me">Mastodon</a>

I can’t find a specific Micro.blog Help article on this. Let me know questions.
