+The meta-emenlow layer contains support for the 'emenlow' machine
+configuration, which makes use of the Intel-proprietary EMGD 1.14
+graphics driver.
+
 To enable the emenlow layer, add the emenlow MACHINE to local.conf:
 
   MACHINE ?= "emenlow"
 
+The 'emenlow' machine includes the emgd-driver-bin package, which has
+a proprietary license that must be whitelisted by adding the string
+"license_emgd-driver-bin_1.14" to the LICENSE_FLAGS_WHITELIST variable
+in your local.conf.  For example:
+
+  LICENSE_FLAGS_WHITELIST = "license_emgd-driver-bin_1.14"
+
 You should then be able to build an emenlow image as such:
