+Using libc for UEFI
+===================
+

+ :depth: 4
+ :local:
+
+Using the UEFI C library
+========================
+
+Once you have finished building the UEFI C library, it
+can be used to run libc or libm functions inside a UEFI
+environment. Current, not all C standard functions are
+supported in UEFI. Consult the :ref:`list of supported
+functions<libc_uefi_support>` for a comprehensive list.
+
+Running a UEFI C library program in QEMU
+========================================
+
+QEMU is the preferred way to test programs compiled using
+the UEFI C library, it only requires OVMF which is based
+on EDKII. It is recommended to create a directory which
+serves as a fat32 file system but passed through QEMU.
+The following flag is capable of doing that:
+
+.. code-block:: sh
+
+ -drive file=fat:rw:fat32-fs
+
+This will expose the ``fat32-fs`` directory as a fat32
+partition. Once QEMU starts, press ESQ a few times to
+bring up the EDKII menu. Enter the boot manager and
+load the option for the UEFI shell. Typically, EDKII
+will expose the fat32 filesystem as ``FS0``. From there,
+you can run the following command to run your program.
+Here, we are using ``a.out`` as the example since clang
+outputs to that filename by default.
+
+.. code-block:: sh
+
+ > FS0:
+ FS0:> a.out
