+# Ntfy
+
+:::info
+This page explains the steps you need to follow to set up the Ntfy
+connection in Automatisch. If any of the steps are outdated, please let us know!
+:::
+
+If you use ntfy.sh, the official public server for this service, you do not need to set up a connection with a custom configuration. It's enough to create one with the default server URL.
+
+However, if you have a ntfy installation, that's different than ntfy.sh, you need to specify your server URL on Automatisch while creating a connection. Additionally, you may need to provide your username and password if your installation requires authentication.
