GoToSocial require a dedicated domain (or subdomain) name, for example: gotosocial.example.com

Please note the following points:

• You will no longer be able to change this domain name once it has been set up GoToSocial.
• If you uninstall GoToSocial, you will no longer be able to use this domain name with another federated software installation, as it will be impossible to reuse the keys used to secure the federation.
• GoToSocial does not provide a user interface.

You will need to use a Mastodon-compatible client such as Tusky on Android, Feditext for iOS or an instance of Semaphore on the Web.
