Safety notes

Be aware that this hub will run in an isolated network on your local machine, and while it will be able to reach out to other sites on the internet, it is not reachable from the outside.

In other words: don't try to connect to other users on real hubs or fediverse instances!

You may want modify the directory mode line in your generated .htconfig.php like this to be on the safe side:

App::$config['system']['directory_mode']  = DIRECTORY_MODE_STANDALONE;
