Pathoschild builds SMAPI and mods, writes modding documentation, supports modders and users, coordinates with the game developers, and nurtures the Stardew Valley modding scene as a full-time hobby.
Hi there! SMAPI will always be free and open-source, but it takes a lot of time (e.g. development, planning, documentation, and support) and money (e.g. server hosting, domains, coffee, etc). Every dollar donated helps support ongoing development and is greatly appreciated!
