+============================
+
+Quick Start
+-----------
+
+- Build the ARM Trusted firmware binary
+- Get scfw_tcm.bin and ahab-container.img
+- Get imx-mkimage
+- Build U-Boot
+- Flash the binary into the SD card
+- Boot
+
+Get and Build the ARM Trusted Firmware
+--------------------------------------
+
+.. code-block:: bash
+
+     $ git clone https://source.codeaurora.org/external/imx/imx-atf
+     $ cd imx-atf/
+     $ git checkout lf-5.10.72-2.2.0 -b lf-5.10.72-2.2.0
+     $ make PLAT=imx8qm bl31
+     $ cp build/imx8qm/release/bl31.bin $(builddir)
+
+Get scfw_tcm.bin and ahab-container.img
+---------------------------------------
+
+.. code-block:: bash
+
+     $ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/imx-sc-firmware-1.11.0.bin
+     $ chmod +x imx-sc-firmware-1.11.0.bin
+     $ ./imx-sc-firmware-1.11.0.bin
+     $ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/imx-seco-3.8.5.bin
+     $ chmod +x imx-seco-3.8.5.bin
+     $ ./imx-seco-3.8.5.bin
+
+Or use this to avoid running random scripts from the internet,
+but note that you must agree to the license the script displays:
+
+.. code-block:: bash
+
+     $ dd if=imx-sc-firmware-1.11.0.bin of=imx-sc-firmware-1.11.0.tar.bz2 bs=42757 skip=1
+     $ tar -xf imx-sc-firmware-1.11.0.tar.bz2

+     $ cp imx-seco-3.8.5/firmware/seco/mx8qmb0-ahab-container.img $(builddir)
+
+Build U-Boot
+------------
+.. code-block:: bash
+
+     $ export ATF_LOAD_ADDR=0x80000000
+     $ export BL33_LOAD_ADDR=0x80020000
