And every other reference, tutorial, book, or video that I've found all points to using LNP which I'm not asking about. The DF documentation is pretty sparse and I haven't been able to successfully install any tileset by following it. I cannot find a single reference anywhere that walks through the process of manually installing a new tileset. I'm gonna attempt to save us all some frustration and emphasize the fact that I'm not asking about LNP or ANY other similar pre-packaged tool.
