 HMDM is a driver mapper which uses any method to allocate kernel memory and any method to copy kernel memory to map unsigned code into the windows kernel. This project is based off of physmeme and is what I intended on creating originally, but was unable to. This repo contains two examples of HMDM, one with VDM (Vulnerable Driver Manipulation of drivers exposing arbitrary physical memory read and write), and the other example using MSREXEC which uses any driver that can write to arbitrary MSR's to elevate to kernel execution. Besides VDM and MSREXEC, one could use any other method of executable kernel memory allocation and arbitrary kernel writes to interface with `drv::hmdm_ctx`.
 
+### Driver Requirements
+
+Driver must be compiled with /GS- and control flow guard disabled. These settings are located in C/C++ --> Code Generation ---> Security Check/Control Flow Guard. The driver
+you compile must have a custom driver entry. This means that you need to change the entry point of the module in linker settings. You can find the setting at Linker --> Advanced --> Entry Point.
+Please make sure that your entry point uses the same function type that HMDM uses. If the function type is changed, please ensure that the changes are also applied to HMDM.
+
+```cpp
+// NOTE: this driver has a custom entry point (drv_entry), if you make a new project
+// please change the driver entry in linker settings... You will also need to disable
+// CFG in c++ --> code generations, along with GS...
+auto drv_entry(uintptr_t drv_base) -> NTSTATUS
+{
+	DbgPrint("> drv base -> 0x%p\n", drv_base);
+	return STATUS_SUCCESS;
+}
+```
