 This tool tries to solve the "OpenGL" problem on nix.
 
+# Quick start

 # Motivation
 
 You use Nix on any distribution, and any GL application installed fails with this error:

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

+# Comparaison with similar tools
+
+[nix-install-vendor-gl.sh](https://github.com/deepfire/nix-install-vendor-gl)
+provides a similar system with a different approach:
+
+- it auto detect the host driver
+- it needs root access and set your system for a specific driver
+- it only provides wrappers for nvidia (without bumblebee)
+
+Both projects are now really similar and the only reason I did not
+contributed to `nix-install-vendor-gl.sh` was because initial `nixGL`
+had a totally different approach.
