If you haven't already, would strongly recommend pinning an introductory toot to your profile. If you have particular images or video or audio you want to feature, they can be attached to pinned toots.

Also, pinned toots are automatically "backfilled" so you never have a blank profile on any server.

To add a pinned toot:

1. Log in with a third party app or through your server's website
2. Go to the toot you want to pin
3. Click ⋯ and "pin on profile"

You can also pin several toots at once!
