 When using the packer tool, the first step is to upload an
 existing CentOS cloud image from the internet into OpenStack.
 Check out: https://cloud.centos.org/centos/7/images/
-You should now source the proper .rc file so Packer can connect to your OpenStack.
+You should now create proper clouds.yaml file so Packer can connect to your OpenStack.
+Sample clouds.yaml could look like this:
+
+client:
+  force_ipv4: true
+clouds:
+  overcloud:
+    verify:    False
+    interface: "public"
+    auth:
+      username:         "admin"
+      password:         "your_password"
+      project_name:     "admin"
+      tenant_name:      "admin"
+      auth_url:         "https://192.168.1.1:5000/v3"
+      user_domain_name: "Default"
+      domain_name:      "Default"
+    identity_api_version: "3"
+
+Packer could be run from docker image, you will need to create following alias:
+
+alias packer='docker run -it -v "$PWD":/root/project -w /root/project hashicorp/packer:light $@'
+
+
 There are 2 files: centos.json and deploycentostools.sh, allowing you to create
 an image automatically. Run
   # packer build centos.json
 Edit centos.json to reflect the settings of your environment: The following fields need to
 be the ID's of your system:
-  - "source_image": Needs to be the id of the Centos cloud image
-  - "flavor": Needs to be the ID of the flavor existing in your OpenStack environment that will be used
+  - "source_image_name": Needs to be the name of the Centos cloud image
+  - "flavor": Needs to be the ID or name of the flavor existing in your OpenStack environment that will be used
     to start the VM in which we will install all tools
   - "networks": ID of the network that will be used for the VM
   - "use_floating_ip": true or false
-  - "floating_ip_pool": ID of the floating ip pool in case floating ip are being used
-  - "security_groups": ID of the security group being used
+  - "floating_ip_network": ID of the floating ip network in case floating ip are being used
+  - "security_groups": ID or name of the security group being used
+
+Refer to Packer docs for more details:
+https://www.packer.io/docs/builders/openstack.html
 
 Note that this procedure is not only installing the necessary tools to run PROX,
 but also does some system optimizations (tuned). Check deploycentostools.sh for more details.
