+ntfy uses "topics" for categorization, which creates a very handy disconnect from
+sender and receiver.<br>
+Lets say there's a minecraft server and there are notifications when someone 
+joins. These notifications are send to a `minecraft` topic, not to a specific users.
+This gives great flexibility and is the main reason why ntfy wins
+over other solutions.
