-> ## CoreAPI for Project Essentials mods.
+### What is it
 
-#### ❗ Compatibility with forge version `28.0.X` and `28.1.X`.
+This is the base module (core) for all other Project Essentials modules. It contains the necessary dependencies that are used in other modules, for example Kotlin std lib and Kotlinx Serialization and Brigadier, this core also contains common code, for example, the initialization process and some extensions of existing forge classes, which can be useful and can reduce duplicate code. For developers, all the information is in the [documentation](documentation/for-developers.md).
