## Compiling
Compiling any of the example client programs is pretty simple. Open the solution file in Visual Studio and compile the project with it's default settings.
Compiling the driver is also pretty simple. First you need a working Linux install (or you can use Linux subsystem for Windows) and install gnu-efi (commands for Ubuntu 18.04):

If the compile was successful, you should now see memory.efi in the driver folder.
**Note:** Some people were reporting that they were unable to compile the driver with some errors related to GUIDs (passing them in as a pointer).

## Usage
In order to use the efi-memory driver, you need to load it. First, obtain a copy of memory.efi ([compile it](https://github.com/SamuelTulach/efi-memory#compiling) or [download it from release section](https://github.com/SamuelTulach/efi-memory/releases)) and a copy of [EDK2 efi shell](https://github.com/tianocore/edk2/releases). Now follow these steps:
