+                    Another example of customizing your image could be setting 
+                    up a read-only filesystem.
+                    Suppose, for security reasons, you need to disable the 
+                    your target device's root filesystem's write permisions
+                    (i.e. you need a read-only root filesystem).
+                    Or, perhaps you are running the device's operating system
+                    from a read-only storage device.
+                    For either case, you can customize your image for 
+                    that behavior.

+                    To create a read-only root filesystem, simply add the 
+                    "read-only-rootfs" feature to your image.
+                    Using either of the following statements in your 
+                    image recipe or from within the 
+                    <filename>local.conf</filename> file found in the Build 
+                    Directory causes the build system to create a
