+# Hexiano to ALSA
+
+This very simple C program makes a virtual ALSA midi device from the
+Hexiano android app
+
+## How it works
+
+It listens for Hexiano logs on the android debug bridge, before using
+this program you'll have to set up the android debug bridge, once
+done you should be able to run `adb logcat` and see everything that's
+happening on your mobile device including the Hexiano events, this
+software basically launches the same command to see what's going on,
+if your command to access the logs is something else than 
+`adb logcat` on your system please change the source code accordingly
+
+## How to compile
+
+`cc -o hexmidi main.c -lasound`
+
+Replace hexmidi with whatever executable name you'd like
+
+Get Hexiano here 
+https://f-droid.org/en/packages/org.gitorious.jamesjrh.isokeys/
+
+(you will require an older android device to run the App)
