installation: fabric

1. Download the Fabric installer from https://fabricmc.net/use/. Similar to Forge, this installer will generate all of the required files for whichever version of Minecraft you select. However, Fabric does not have multiple installers for each version and you can install any version you want via the same installer.
2. Open the Fabric installer, which should automatically have the Client tab selected at the top.
   
3. Select the Minecraft version you want to install onto your client. You can also select a version for the Fabric Mod Loader here, although it's normally best left on the latest version unless required by a specific mod.
4. Ensure that the install location is set to the correct place. The correct location varies per operating system and install, but should look something like one of these depending on your platform:
   • Windows: %AppData%/.minecraft or C:/Users/(username)/AppData/Roaming/.minecraft
   • MacOS: ~/Library/Application Support/minecraft
   • Linux: ~/.minecraft
5. If you'd like the installer to automatically create a selectable profile within your Minecraft launcher, make sure the Create profile box is checked.
6. Click the Install button, and your install should complete within a few seconds! After that, click OK and close off the installer.
   1. Open the Minecraft Launcher and the newly created Fabric profile should automatically be selected. Click Play, and your Fabric install will load up.
