+This repository contains the scripts used to parse, clean and analyze the raw
 experimental data for the MechaRaptor.
 
 ## Data
 
 The data come from three different sources:
 
-1. Wind tunnel itself (`<YYYY>-Serie<X>-Identification.csv`)
+1. Wind tunnel itself
     - airspeed
     - atmospheric pressure
     - the temperature
-2. Wind tunnel load sensors (`wtFiles/`):

     - Measure of forces and moments in three axes
-3. Arduino acquisition (`arduinoFiles/`):
+3. Arduino acquisition
     - Measure of wing angles
     - Measure of electrical power (tension and current)
     - Input values
 
+Raw data and details about them can be found in their respective repositories
+(loaded as submodules).

 ## Scripts
 
-[TODO]
+The scripts were made in a rush and are currently a bit messy. They will be
+reworked properly in the following weeks before the start of a more extensive
+wind tunnel testing campaign.
