 To use the experimental version of the embedded software (firmware)
 as well as system configuration, you must build the 'meta-xilinx-setup'
-SDK.  This SDK is passed a device tree, constructed from DTG++ and
+SDK.  This SDK is passed a device tree, constructed from System Device tree and

+3. Install the setup SDK:
+```
