 Helper interface and CLI to interact with [luxafor](https://luxafor.com) products.
 
+## Install
 
-## Usage

+
+## Using the CLI
+
+Pyluxafor provides the `luxa` command to interact with the USB led in the same way as the library
+does, with some helper commands to convert colors between RGB/Hex.
+
+```
+# Converts between hexadecimal to decimal color notations
+luxa hex2dec 00ff00
+luxa dec2hex 255 255 0
+
+# Set a flag with a fixed color
+luxa set --led=all #ff0000
+
+# Fade
+luxa fade --led=all --speed=10 #00ff00
+
+# Strobe
+luxa strobe --led=front --speed=100 --repeat=10 #0000ff
+
+# Wave
+luxa wave --wave 3 --duration=100 --repeat=200 #ff0000
+
+# Pattern
+luxa pattern --repeat=2 2
+
+# Turns off the luxafor
+luxa off
+
+# Using the conversion helpers in one command
+luxa set $(luxa dec2hex 255 0 0)
+```
+
+## Using as a library
 
 ``` python
 from luxafor import luxafor
