 Building Zephyr Images via bitbake recipes

 Modify local conf by adding:

 Add "meta-zephyr" to BBLAYERS
 
+Building and Running Zephyr Samples
+===================================
 
-Building and Running Zephyr tests
+You can build Zephyr samples. There are several sample recipes.
+For example, to build the Zephyr "philosophers" sample:
+    
+    $ MACHINE=qemu-x86 bitbake zephyr-philosophers
+    
+You can then run the created "philosophers" image in qemu:
+
+    $ runqemu qemu-x86
+    
+The same sample, for ARM image:
+
+    $ MACHINE=qemu-cortex-m3 bitbake zephyr-philosophers
+    $ runqemu qemu-cortex-m3

+The same sample, for Nios2 image:

+    $ runqemu qemu-nios2
