Crosstone is designed for if you have or would prefer to tonemap your albedeo (ideally lower resolution additional maps rather than your albedo to make maximum use of the feature). You can use photoshop to paint/adjust them yourself, but basically it's just one or more additional textures to provide the shadowtone blending, or you just overlay the color.

The manual is wonderful and not all that complicated to follow. 
The results you get can be really cool. 
If you want to go extremely next level create a tightly packed, dense tiled detail maps for the skin of your model (separate the material) and you'll get toon shading that actually glistens in the sun, you festive degenerates.
