Where to add more description to units?

[Filius-Patris]

I think the Units section needs some love. For example there's no way to find out what unit gets created when you upgrade a unit.

I would like to contribute to that, but I don't know how to override the description (it seems generated?). I don't want to remove the useful infos like the stats box and the in-game description, I just want to add.

Anyone mind guiding me a bit? Thanks!

I think this issue is better located on the generator wiki...
