Hey guys, I'm the dev. The reason I haven't published a readme or install help is not that I "don't care," it's that I had yet to post this github anywhere and it is nowhere near ready for release. the filestructure under the main branch on my github is the dev filestructure, used by the MSFS SDK. in this filestructure, the generated packages (the ones you want to use) are always under /Packages in the main folder. OP got in contact with me directly on github so there's now a release published if you want to use it, it is better than default I suppose, but just know it's not done. In any sense.
This release has the proper drag and drop file structure, simply extract the zip and move the resulting truemetro-airport-kiag-niagara folder to Packages/Community.

Happy landings.
