+## XT Development Kit (XTDK)
+The XTDK, or XT Development Kit is a comprehensive set of headers designed to facilitate the development of both kernel
+mode drivers and native XT applications. It includes two main headers: xtkmapi.h and xtumapi.h.
+
+The xtkmapi.h header is primarily used for kernel mode development, specifically for building drivers. It provides
+developers with the necessary definitions and functions required to interact with the kernel and access system
+resources. With this header, developers can write efficient and secure kernel mode drivers for the XT operating system.
+
+The xtumapi.h header is tailored for user mode development. It encompasses all the essential components needed for
+creating user mode applications on the XT platform. This header exposes the definitions and public functions exported by
+XTOS, allowing developers to leverage the capabilities of the operating system and build powerful user mode applications.
+
+By utilizing XTDK, developers can harness the full potential of the XT operating system and seamlessly write both kernel
+mode drivers and user mode applications. The provided headers streamline the development process by offering
+a standardized set of functions and definitions, reducing the complexity and effort required to create software for the
+XT platform.
