+# One Step from Eden Standalone
+
+Proposal for Standalone Support for One Step from Eden
+
+## One Step from Eden Modding Intro
+
+One Step from Eden supports mods via LibHarmony and the Steam workshop
+
+LibHarmony allows you to patch a large variety of things in the
+C# application it is loaded in, and we can use this to essentially
+patch any method or class that we would like to patch.
+
+## Hardcore Implementation
+
+There are two methods to install mods. One is through the Steam Workshop
+and the other is through the local Mods folder.
+
+The local mods are always loaded and they are loaded before Steam Workshop mods.
+They can also be assigned a priority to prefer some local mods over others.
+
+Steam workshop mods can be toggled active or inactive and they can be also be assigned a priority.
+Most mods assign a priority of 0, some have a higher finite value (i.e. MoreLuaPower uses 1000).
+
+RetroAchievements must load before any other mod to enforce hardcore mode restrictions,
+so we should assign ourselves a priority of "+Infinity" and check that there are no local
+mods installed (we should be a Steam workshop mod) and that all other mods have finite priorities.
+
+Of course, anyone could cheat and load before us and mess with this process, but it's
+useful to prevent accidental mod loading and make it a bit harder for people to cheat.
