+# yamahactrl
+
+## What is it?
+Small simple bash script for basic control of Yamaha RX-V amplituner series.
+
+## Why?
+I've written it just because the only other application I found was written in node js, which I've found to be an overkill for my simple needs.
+
+If you need more functionality, you should probably check out this: https://github.com/ttu/node-yamaha-avr
+
+## Usage
+```
+./yamahactrl.sh
+Bash script to control Yamaha Amplituner RX-V series.
+Usage: ./yamaha.sh command
+
+Possible commands:
+ -volup		 Set volume up by 1
+ -voldown	 Set volume down by 1
+ -on		 Set power on
+ -off		 Set power off
+```
+
