 The original library has been converted to a Header Only C++ Library. Unlike the original implementation, we can feed the parser incrementally with data. This is important if you want to use it on a microcontroller that has only a limited amount of RAM.

+## Installation in Arduino
+
+For Arduino you can download the library as zip and call include Library -> zip library. Or you can git clone this project into the Arduino libraries folder e.g. with
+```
+cd  ~/Documents/Arduino/libraries
+git clone https://github.com/pschatzmann/arduino-midi-fileparser
+```
+
+## Building the Example on the Desktop
+
+You can build the example sketch on the desktop 
+```
+cd ~/Documents/Arduino/libraries/libraries/arduino-midi-fileparser/examples/midi-parse
+mkdir build
+cd build
+cmake ..
+make
+```
