-# S1API - A Schedule One Mono / Il2Cpp Cross Compatibility Layer
-S1API is an open source collaboration project to help standardize Schedule One modding processes.
-The goal is to provide a standard place for common functionalities so you can focus on making content versus reverse engineering the game.
-
-> **This GitHub repository is intended for developers.**
-> If you are just looking to mod your game, please refer to the releases / mod repositories such as Thunderstore and Nexus Mods.
-
-## What Does it Do?
-* Allows creation of new game elements (quests, npcs, etc.)
-* Provides an easy-to-use abstraction for save/load of class data
-* Eases access to various common game functions without needing to import the assembly themselves, removing the Mono / Il2Cpp dependency for your mod.
-* Allow modders to live in the Managed environment, regardless of Mono / Il2Cpp development
-* Lower the bearer of entry into S1 modding, especially for Il2Cpp builds
-* Support mod developers by allowing them to compile a single assembly that works across both builds
-* Who knows what else? We will have to see who all is willing to collaborate on this ❤️
-
-## What Are the Limitations?
-* S1API will NOT be the be-all and end-all. It's just not possible.
-* Handle Il2Cpp / Mono communication when utilizing game assemblies as dependencies
-* Cover all modding needs. It will never be as flexible as writing your own mod referencing game assemblies.
-
-## How It's Designed to Work
-S1API is designed to compile for Mono and Il2Cpp separately.
-Mod users install the version applicable to they're preferred build.
-
-Mod developers can develop their mods on whichever build, Mono or Il2Cpp, without having to step into the Il2Cpp environment.
-Caveat: If you do utilize Il2Cpp functionality within your mod, you lose cross compatibility.
-I can't think of why you would. I wanted to make sure that is clarified though.
-
-S1API is designed to be a tag-along as well.
-If you want to do custom content specific to Mono or Il2Cpp, S1API can still assist with some of the common repetitive tasks.
-
-## Want to Contribute?
-This is a massive project with so many different areas to specialize in.
-If you're interested in contributing, please do!
-Look over the [CONTRIBUTING.md](CONTRIBUTING.md) for guidance on code standards and the process.
