+## Description
+Packer files for creating virtual machine image used for Nordix NSM build server.
+
+## Steps To Run
+ 1. Source OpenStack RC file `source <openstack-rc-file.sh>`to set environment variables used by packer e.g. OS_USERNAME, OS_PASSWORD and OS_AUTH_URL
+ 2. Run `packer build <packerfile.json>`
+
+This will create the image specified on OpenStack.
+Modify packer parameters as required and add packages to be installed into the shell script.
+For more info, see [Packer docs](https://www.packer.io/docs/builders/openstack)
