+            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.

+            1. Enable **Websocket Support**
+            2. Change the admin credentials
