+            Owncast is for people who are live streamers, or who wants to host live streams for others.
+            It's a "one to many" broadcast much like Twitch, Facebook Live, YouTube Live, etc.
+            The default RMTP port is `1935` (can be changed in the admin panel) and may need to be opened in your firewall.

+            Owncast has been successfully deployed! It might take few moments before it's fully started.
+            You can access the admin panel at http://$$cap_appname.$$cap_root_domain/admin with username `admin` and password `abc123`.
+            Please do the following steps:
+            1. Enable **Websocket Support**
+            2. Change the admin credentials
+            3. If you changed the RMTP port, adjust it in the admin panel
