 Touchless 3D Tracking
 ===================
+----
 
-A script to pick a color (and more coming) using a touchless 3D hand tracking system with aluminium foil.
+This is based on an original project by [Kyle Mc Donald](https://github.com/kylemcdonald) : http://www.instructables.com/id/DIY-3D-Controller/.
+
+Our slightly adapted setup is documented on my hacklab website [hackens.org](http://hackens.org/). All the documentation can be found here : **(documentation to be written)**.
+
+In this repository, you'll find :
+
+- A script to upload on the Arduino (we used an Arduino Uno) in the touchless_tracking folder
+- Some python scripts to play with it on your computer
+
+## Arduino script
+
+Basically, the Arduino script reads discharge times for the three electrodes (this time is related to the distance between your hand and the electrode). 
+It returns formatted lines on the Serial output like the following line :
+
+```
+value1␣value2␣value3␣\n
+```
+
+where `value1`, `value2`, `value3` are values directly proportional to the discharge time for the electrode (see the code for more infos).
+
+## Python scripts
+
+You'll also find some basic Python scripts as examples on possible use of the setup.
+
+### Colors.py
+
+This script represents the position of your hand in the RGB space. You can then pick a color by placing your hand at a specific point in the box of the electrodes.
+
+### Some ideas (TODO List)
+
+* Same as colors.py but representing it with a 3D view.
+* Then, use the previous code as a control interface for your computer, just like Minority Report :)
+* Other ideas ? It's up to you :)
