+===========================================================
+Instructions:
+
+To build a "devcloud base box", run you need a system with VirtualBox and rvm
+installed (use ruby 1.9.2).  Run build_vagrant_basebox.sh to build the base box.
+
+To use the "devcloud base box" that is created in the previous step, you
+need to have installed a forked version of Vagrant (until we make the changes
+plugins instead of direct source patches) that can be found here:
+
+
+Once installed per the Vagrant installation process, run:
+
+vagrant box add devcloud [path to devcloud.box]
+
+Then, either go into the devcloudbox folder of your checked out 
+version of the CloudStack code (incubator-cloudstack/tools/devcloud/devcloudbox),
+or copy the contents of that folder to another location.
+
+Assuming the patched Vagrant installation is working, you then
+simply run "vagrant up" from within that directory.
