 # MiniCore
 An Arduino core for the ATmega8, ATmega48, ATmega88, ATmega168 and ATmega328, all running a [modified version of Optiboot](#write-to-own-flash). This core requires at least Arduino IDE v1.6, where v1.6.5+ is recommended. <br/>
-If you're into "pure" AVR programming, I'm happy to tell you that all relevant keywords are being highlighted by the IDE through a separate keywords file. Make sure to test the [example files](https://github.com/MCUdude/MiniCore/tree/master/avr/libraries/AVR_examples/examples) (File > Examples > AVR C code examples).
+<b>This core gives you two extra IO pins if you're using the internal oscillator!</b> PB6 and PB7 is mapped to [Arduino pin 20 and 21](#pinout).<br/>

 MiniCore works perfectly with Eclipse using the [Arduino Eclipse plugin](http://eclipse.baeyens.it) (formally Sloeber). If you're tired of Arduino IDEs limits but still want to stick with open source software; this is the way to go!
