 # Limitations
 
-The idea is really simple and should work reliably in most cases. It
-can be easily extended to AMD drivers, I just don't have the hardware
-to test. Contact me.
-
-*Important*: You need an host system driver which match the nixpkgs one. For example, at the time of this writing, nixpkgs contains nvidia `390.25`. Your host system must contain the same version. This limitation can be lifted by using a different version of nixpkgs:
-
-```shell
-export NIX_PATH=nixpkgs=https://github.com/NixOS/nixpkgs-channels/archive/nixos-14.12.tar.gz
-nix-build -A nixGLNvidia
-```
-
-Contact me if this limitation is too important, it may be easy to automate this process.

+Does not work now for AMD drivers because I dont' have the hardware.
