+      description: If your issue is related to an exception make sure the error was thrown by Discord.Net, and not your code or another library. 
+                  If you get an `HttpException` with the error code `401`, then the error is caused by your bot's permissions, not dnet.

+      description: If your issue is related to not receiving expected events, you may have setup your gateway intents incorrectly. 
+                    Newer versions of Discord.Net use a more modern version of Discord's API that requires you tell it what events
+                    you want to receive. Discord.Net defaults to all non-privleged intents, but if your bot requires privileged intents 
+                    you need specify them in your clients config. You can see what intents you need for your events 
+                    [here](https://discord.com/developers/docs/topics/gateway#list-of-intents).
