The Architectury API is a small library that is needed to run some mods. Using it, developers can quickly create mods for two loaders at the same time (Forge and Fabric). Users need it only if the instructions for installing the mod require it. If you need this library for Fabric, you can download it here.
How to install Architectury API
- Make sure you have installed Minecraft Forge.
- Download the mod for your version of the game.
- Put it in the ‘mods’ folder, which is located in the game folder.
