This has come up as an issue sometimes in regards to whether or not this mod is actually open source. Some say it's not because, implicitly, it means that the project is all rights reserved. I wish that there was an actual LICENSE file to accommodate the project so there won't be any ambiguities/guesses.

This seems like the license we'd need here. https://github.com/Aroma1997/CompactWindmills/blob/master/license.txt
