configuration file, located at config/spyglass-astronomy-sync.json.

}
- Set
allow_admin_commandstotrueto allow all/sga:admincommands for every player. Note that players with
permission level 2 or higher will bypass this setting. - The configuration file is only read at server startup. Restart the server after making changes for them to take
effect.
Dependencies
To use Spyglass Astronomy Sync, the following are required:
- Fabric API
- Spyglass Astronomy on the client (server does not need it).
Both the server and the client must have Spyglass Astronomy Sync installed for the synchronization to take effect.
