If you're just getting started with modding hollow knight, you should start with the Getting Started Guide to get your system setup for modding. The Hollow Knight Modding Api is based on MonoMod, a General purpose. This is achieved with the help of a Modding Api that handles the loading of mods and giving us ways of injecting our own code in the middle of normal logic. Hollow Knight (patch 1.5.x.x onwards) is a game built with Unity 2020.2.2 and C# (.NET Framework 4.7.2), this means that a mod in the context of hollow knight is a dll or a Dynamic-Link Library that allows players to modify the behavior of the game, fix issues or add new features.
