+## XT Boot Manager (XTLDR)
+The XTLDR, or XTOS Boot Loader, is an EFI (Extensible Firmware Interface) boot loader specifically designed for XTOS.
+As an EFI boot loader, XTLDR operates exclusively with EFI-based hardware and is not compatible with non-EFI systems,
+like old and deprecated BIOS.
+
+One of the notable features of XTLDR is its modular design. The boot loader is divided into different modules, with only
+the essential core being loaded during the boot process. This modular approach allows for a more efficient and
+streamlined boot experience, as only the necessary functionality is loaded, reducing the boot time and system resource
+usage.
+
+XTLDR includes various modules that provide specific functionalities required for the boot process. For example, there is
+a module dedicated to supporting the XTOS boot protocol, which is the specific protocol used by XTOS for loading and
+executing the OS kernel. Additionally, there is a module for handling PE/COFF (Portable Executable) binaries, which is
+a commonly used format of executable files used by the XTOS.
