 ## Unlocking Internal iGPU
 
-The `apple-set-os-loader-installer.nix` module serves as an installer for the [`apple-set-os-loader`](https://github.com/Redecorating/apple_set_os-loader). This tool is designed to unlock the internal integrated GPU (iGPU) on certain MacBooks. See https://wiki.t2linux.org/guides/hybrid-graphics/ for more details.
