+## What is this?
+KessokuLib is a cross-platform modular library for Minecraft: Java Edition.
 
-#### [HOW TO ADD MODULE](./ADD-MODULE.md)
+It is intended to provide a unified intermediate API between mod loaders (we don't provide anything like Connector, I don't see the benefit of providing something like Connector, on the contrary it would probably bother mod developers more).
+
+We have incorporated the benefits of each platform's API into this mod's API in order to simplify mod development.
+
+## Why do you need a cross-platform API?
+This means that most of your code is generic and only some of it is individually specific to a platform, which is even more important for developing.
+
+One Code, Each Platform. -- By H2Sxxa
+
+## What is the current stage of development of this library?
+Still in WIP.
+
+## What about the language loader?
+Kessoku Languages is currently in EAP status, but all we can guarantee at the moment is that we can provide language loaders with Kotlin/Scala/Groovy.
