A set of nodes and sample shaders to make NPR shading in Blender Eeevee easier.
On GitHub head over to Releases and download the latest release. Inside the zip file you'll find another zip which you can add to blender's add-ons (Edit->User Preferences...->Add-ons->Install Add-on from file...).
This is work in progress, as is Blender 2.8.
