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.


📖 Description
This mod shows you the properties of all blocks & items (vanilla + modded) as tooltips and JEI/REI/EMI info pages! Useful for mapmaker, pack maker, modder and redstoner!
With many config options to customize it to your liking.
