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.

The mod is built to be lightweight and easy to use. Hope you enjoy it! 中文：这是一个令人惊叹的模组，他修改了原版的堆叠上限，你只需要输入/max stack [数字]就可以设置为堆叠上限，最高是9999，且真实有效，模组以轻量化和易用性而建造，欢迎您的使用！
