+
+Usage
+=====
+
+1.- Clone this layer along with the specified layers
+
+2.- $ source oe-init-build-env
+
+3.- Add this layer to BBLAYERS on conf/bblayers.conf
+
+4.- Add the following to your conf/local.conf to build for the microblaze architecture:
+
+DISTRO="xilinx-standalone"
+
+MACHINE="zynqmp-pmu"
+
+GCCVERSION="7.%"
+
+5.- Build a package:
+
+for example:
