Installation
Automatic
In the Modrinth App, Prism Launcher, or ATLauncher, there should be added a new instance with the downloaded mrpack file imported. If the version is not detected, 1.21.11 with the most recent version of Fabric mod loader must be used
Manual
First, downloaded mrpack file needs to be converted to zip using an external tool. If it has never been done, Fabric installer must be downloaded and ran with the most recent loader version for 1.21.11 chosen. After that a new instance should have been created in the game launcher
Next - inside .minecraft in the %appdata% file directory in Windows, ~/Library/Application Support/minecraft in macOS, or ~/.minecraft in Linux - config, mods, resourcepacks, shaderpacks, and options.txt (provided they exist) have to be removed and then replaced with the contents of the zip file
