+Role Name
+=========
+
+An Ansible role for scaling and deleting nodes from an overcloud.
+
+Requirements
+------------
+
+This role assumes it will be executed against a host on which a Liberty or Mitaka under/overcloud have already been deployed.
+
+**Note:** The ansible-role-tripleo-overcloud-validate role must be accessible.
+
+Role Variables
+--------------
+
+A description of the settable variables for this role should go here, including any variables that are in defaults/main.yml, vars/main.yml, and any variables that can/should be set via parameters to the role. Any variables that are read from other roles and/or the global scope (ie. hostvars, group vars, etc.) should be mentioned here as well.
+
+**Note:** Make sure to include all environment file and options from your [initial Overcloud creation](https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux_OpenStack_Platform/7/html/Director_Installation_and_Usage/sect-Scaling_the_Overcloud.html#sect-Adding_Compute_or_Ceph_Storage_Nodes). This includes the same scale parameters for non-Compute nodes.
+
+- artosn_scale_nodes: <true> -- boolean value that will scale nodes if true
+- artosn_delete_original_node: <false> -- boolean value that will delete the original node of type that was scaled
+- artosn_working_dir: <'/home/stack'> -- working directory for the role. Assumes stackrc file is present at this location
