Hello! How can I add a <link> tag to the admin page? Where is this page?
Where exactly do you want to create a link and where to should this link to?
luceos In the head section of the admin panel
glo I don't think there are extensions that allow adding links to the admin top navigation. But one could be build. The extend documentation is at https://docs.flarum.org/extend or you can suggest such a feature on our proposals tag or commission it under the services tag.
