+Currently the project is configured to use gdrv, but if you want to swap the driver out you must defined four functions. 
+
+### vdm::load_drv
+
+Replace this function with the code required to load your driver... Return an std::pair containing the driver handle and an std::string containing the registry key name
+for the driver. The key name is returned from [loadup](https://githacks.org/xerox/loadup).
+
+```cpp
+__forceinline auto load_drv() -> std::pair <HANDLE, std::string>
+{
+	const auto [result, key] =
+		driver::load(
+			vdm::raw_driver,
+			sizeof(vdm::raw_driver)
+		);
+
+	if (!result) 
+		return { {}, {} };
+
+	vdm::drv_handle = CreateFile(
+		"\\\\.\\GIO",
+		GENERIC_READ | GENERIC_WRITE,
+		NULL,
+		NULL,
+		OPEN_EXISTING,
+		FILE_ATTRIBUTE_NORMAL,
+		NULL
+	);
+
+	return { vdm::drv_handle, key };
+}
+```
