+================
+opensuse-minimal
+================
+
+This element will build a minimal openSUSE image. It requires 'zypper' to be
+installed on the host.
+
+These images should be considered experimental. There are curently only x86_64
+images.
+
+Environment Variables
+---------------------
+
+DIB_RELEASE
+  :Required: No
+  :Default: 42.1
+  :Description: Set the desired openSUSE release.
+
+DIB_OPENSUSE_MIRROR:
+   :Required: No
+   :Default: http://download.opensuse.org
+   :Description: To use a specific openSUSE mirror, set this variable to the
+                 mirror URL before running bin/disk-image-create. This URL
+                 should point to the root directory as indicated in the
+                 http://mirrors.opensuse.org/ webpage. You normally
+                 don't want to change that since the default setting will
+                 pick the mirror closest to you.
+   :Example: ``DIB_OPENSUSE_MIRROR=http://ftp.cc.uoc.gr/mirrors/linux/opensuse/opensuse/``

+features:
+  - New zypper-minimal and opensuse-minimal elements to create basic
+    openSUSE images. These two new elements are also making use of the
+    existing zypper element which has been extended to include the
+    functionality previously present in the opensuse element.
