Java is easiest to setup for the client, but the frequency of updates means that it may stop working in the future. The Medieval Faire Minecraft server works with the most currrent (1.19.2) version. Start your launcher, make sure the Latest Version is selected and click Play. Once the client is running, you then click "Mulitplayer" and then "Add server" and put in the server settings below, then double click the new server to join the world.
