+### Building a driver
+
+There are three types of UEFI executables: application, boot service
+driver, and runtime driver. All of Rust's UEFI targets default to
+producing applications. To build a driver instead, pass a
+[`subsystem`][linker-subsystem] linker flag with a value of
+`efi_boot_service_driver` or `efi_runtime_driver`.
+
+Example:
+
+```toml
+# In .cargo/config.toml:
+[build]
+rustflags = ["-C", "link-args=/subsystem:efi_runtime_driver"]
+```
+
 ## Testing
 
 UEFI applications can be copied into the ESP on any UEFI system and executed
 via the firmware boot menu. The qemu suite allows emulating UEFI systems and
 executing UEFI applications as well. See its documentation for details.

 it via `cargo install uefi-run` and execute qemu applications as
