Category:Shop Tile Framework
"Shop Tile Framework (STF) is a tool for Modders of the game Stardew Valley, which allows you to define shops via a shops.json file. These shops are attached to tile properties which can be loaded anywhere into the game with another method. Content packs need a shops.json to define their shops."
STF can be used to modify Vanilla shops like Peirre's and JojaMart as well as custom shops you define in your mod.
