Install & use Install: SMAPI mod (Stardew Valley standard)

  1. Install SMAPI first (Stardew Valley's mod loader): download it from smapi.io, run 'install on Windows.bat' and pick your game folder.
  2. Unzip the archive from playbuff and find the folder that contains manifest.json — that folder is the mod.
  3. Copy that whole folder into Stardew Valley/Mods/.
  4. Launch the game through SMAPI (run StardewModdingAPI.exe or set it as the launch option). The console before the title screen lists each mod's load result.

Cheat-style tools may not need SMAPI — unzip and run them as the readme describes. Back up your save before editing it; SMAPI lists failed mods in its console.
