Changes

A SMAPI mod uses the [https://smapi.io/ SMAPI] modding API to extend the game logic. SMAPI provides events so mods The mod can respond when something happens in the game (like when an object is placed in the world), or run code periodically (like once per update tick), change the game's assets and data, etc. SMAPI mods are written in C# using the .NET Framework, and Stardew Valley uses XNA/MonoGame for the game logic (drawing to the screen, user input, etc).
