 Use Fedora cloud images as the baseline for built disk images.
 
+If you wish to use a Fedora Yum mirror you can set DIB\_DISTRIBUTION\_MIRROR
+before running bin/disk-image-create. Example:
+
+  DIB\_DISTRIBUTION\_MIRROR=http://download.fedoraproject.org/pub/fedora/linux
+
+This URL should point to the directory containing the releases/updates/
+development/and extras directories.
+
 For further details see the redhat-common README.
