+## 2ner: a toon shader
+
+2ner is a toon shader for Unity's built in render pipeline. It is my second
+toon shader, replacing github.com/yum-food/Tooner.
+
+It's a ground-up rewrite taking into account some key lessons from last time:
+
+1. Performance perfectionism really is required for realtime graphics
+   1.1. "You don't pay for what you don't use" must be respected!
+2. Tooling is absolutely required to mitigate performance creep, minimize
+   compilation times, and reduce the risk of hitting compiler bugs.
+   2.1. Yes, I have hit compiler bugs!
+
+As with Tooner, it is an all encompassing uber shader. The goal is to expose
+feature rich abstractions for both avatars and worlds.
