How can I tag a package?

On JuliaHub I can search for packages by “tag”. How can I add tags to my own packages?

On GitHub on the right there is “About”. You can edit your “About” and add “Topics”. Those are visible as Topic on JuliaHub. The term “tag” is now only found in the search description of JuliaHub. I am unsure, but I think “Topics” have been named “Tags” earlier, but I missed the change or any notification about this.
