 The main goal is to be able to make BIOS Setup screenshots for systems without serial console redirection support, but it can also be used to take screenshot from UEFI shell apps and UEFI bootloaders. 
 
 To start the driver, you can either:
-- Integrate it into DXE volume of your UEFI firmware using [UEFITool](https://github.com/LongSoft/UEFITool) or any other suitable software
+- Integrate it into DXE volume of your UEFI firmware using [UEFITool](https://github.com/LongSoft/UEFITool) or any other suitable software (don't forget a DepEx section to prevent too early start)
 - Add it to an OptionROM of a PCIe device (will try it once I have a device needed)
 - Let BDS dispatcher load it by copying it to ESP and creating a DriverXXXX variable
 - Load it from UEFI Shell with load command
