 ===========
 
+This project is an attempt to create optimized version of an openFrameworks projection mapping addon for the Raspberry Pi.

 Introduction
 ------------
-openFrameworks addon for doing projection mapping with the Raspberry Pi. This is a placeholder. The addon itself is work in progress. Comming soon!
+ofxPiMapper is mainly intended for people who want to use the Raspberry Pi as a cheaper way to create standalone mapping installations. Let's say someone has 10 generative mapping pieces and at last get's an offer to exhibit them in an art or any other kind of gallery. 10 Mac computers? No! PiMapper is here to save you!
