Connecting to MewChat is simple.
For this tutorial, I will be using Konversation on Artix Linux but you can use any IRC client to connect. The steps may differ from client to client though!
First of all, press F2 to open the server list menu.
Then, click "New".
Fill out the details as shown in the pictures below.
Now save the details, right click on MewChat on the sidebar and hit connect!
