+### Example Thing Definition
+
+The easiest method to add Minecraft servers, players, and signs is use the automatic discovery through Paper UI. However, you can manualy define the objects using thing configuration files. Players and signs are connected through Minecraft server [bridges](https://www.openhab.org/docs/configuration/things.html#defining-bridges-using-files).

+```xtend
+Bridge minecraft:server:myminecraftserver "Minecraft server for Friends" @ "Minecraft" [ hostname="192.168.1.100", port=10692 ] {
+ Thing player my_name "My Minecraft User" @ "Minecraft" [ playerName="minecraft_username" ]
+ Thing player friends_name "My Friend's Minecraft User" @ "Minecraft" [ playerName="friends_username" ]
+ Thing sign sign_name "Example Sign" @ "Minecraft" [ signName="sensor" ]
