+Mesos elements
+==============
+
+This directory contains `[diskimage-builder](https://github.com/openstack/diskimage-builder)`
+elements to build an image which contains mesos and its frameworks required to
+use the heat template mesoscluster.yaml.
+
+Currently, only Ubuntu 14.04 is supported. An example Ubuntu based image can be
+built and uploaded to glance as follows:
+
+    sudo apt-get update
+    sudo apt-get install git qemu-utils python-pip
+    sudo pip install pyyaml
+
+    git clone https://git.openstack.org/openstack/magnum
+    git clone https://git.openstack.org/openstack/diskimage-builder.git
+    git clone https://git.openstack.org/openstack/dib-utils.git
+    export PATH="${PWD}/dib-utils/bin:$PATH"
+    export ELEMENTS_PATH=magnum/magnum/templates/heat-mesos/elements
+    export DIB_RELEASE=trusty
+
+    diskimage-builder/bin/disk-image-create ubuntu vm docker mesos \
+        -o ubuntu-mesos.qcow2
+
+    glance image-create --name ubuntu-mesos --is-public True \
+        --disk-format=qcow2 --container-format=bare \
+        --property os_distro=ubuntu --file=ubuntu-mesos.qcow2
