What is it?
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
Recommended to use Hey Wiki instead!
Allows to search any block/entity that player is looking on or item on cursor on minecraft.wiki by pressing a keybing (by default 'O')
Works for every language, that Minecraft Wiki supports. Other languages will use translation key for search.
