 ### Building
+
 Building the application requires the target `x86_64-unknown-uefi` to be installed on your machine. Install it by running `rustup target add x86_64-unknown-uefi` in command shell.
 
 After the target is installed, build the application with the command `cargo build --target x86_64-unknown-uefi`. When the build completes the resulting EFI application `my_efi_app.efi` will be found in `target\x86_64-unknown-uefi\debug\`
