 ## Usage
 
-The add-in is activated by opening the **xDGA.ADDIN64.xll** or **xDGA.ADDIN.xll** file, depending on your architecture. Both files are in the **Distribution** folder and they are stand-alone (i.e. don't need other files or libraries to run).

+This is a helper function that prepares DGA data in a way that can be fed into any of the funcitons that require it.
 
 For example, the IEC_60599() function takes in the Current and the Previous DGA as well as a boolean value indicating whether the transformer has an On-Load Tap Changer (OLTC) and the volume of oil in the tank in litres.
