+## Boot the Open OnDemand node
+
+A primary function of this project is to provide a dev/test cluster for working
+with Open OnDemand.  After the cluster is up boot the ood node with:
+```
+vagrant up ood
+```
+
+This will provision the node and near the end of the provisioning provide several
+sudo commands that need to be run on the ohpc node to register the ood node
+with the cluster, ensuring data synchronization and slurm work.
+
+After the node is provisioned (or booted) you need to work around mount issue
+with NFS mounts and issue the `mount -a` command on the ood node:
+```
+vagrant ssh ood -c "sudo mount -a"
+```
+
+After this point you can connect to the web ui of the ood node, typically via

+The default user name and password for the web UI is 'vagrant'.
