 # AVR Projects
 
-This repository holds my AVR projects. They're mostly too small to be worth a separate repository.
+*This repository contains all my AVR projects.*
 
-Any code here is free to use in your projects, according to the MIT license.
+Most are in C, to be compiled with `avr-gcc`. There's always a `Makefile` that should take care of it.
+
+## Hardware
+
+Some projects are for `ATtiny13` or `ATtiny2313`, some bigger ones are for *Arduino Pro Mini*,
+but in plain C, not the ugly Arduino C/C++ hybrid.
+
+I use the Arduino Pro Mini, because it's the cheapest way to get an `ATmega238P`, already with
+a nice breakout board, crystal and everything. They can be purchased on eBay for under $3 (USD)!
+
