 > * To use this layer you must REMOVE meta-xilinx-tools from your project.
 meta-xilinx-tools is not compatible with this experimental approach. You may
 also have to remove other layers that depend on meta-xilinx-tools, such as
 meta-kria and meta-system-controller.
+> * Follow [System Device Tree Instructions](https://github.com/Xilinx/system-device-tree-xlnx/blob/master/README.md)
+>   to generate the SDT output.
 > * To use the experimental version of the embedded software (firmware) as well
 as system configuration, you must build through gen-machineconf tool. This tool
 is passed a output of system device tree directory.
