+Configure Postgresql
+=========
+
+- Configure Postgresql
+- Create user and database
+- Create cron job for backup
+  Requirements
+
+------------
+
+Any pre-requisites that may not be covered by Ansible itself or the role should be mentioned here. For instance, if the
+role uses the EC2 module, it may be a good idea to mention in this section that the boto package is required.
+
+Role Variables
+--------------
+
+- db_name
+- db_user
+- db_password
+- db_version
+- host_ip
+- allowed_db_ip
+- db_port
+
+Dependencies
+------------
+
+Use this role only after postgres-install
+
+Example Playbook
+----------------
+
+Including an example of how to use your role (for instance, with variables passed in as parameters) is always nice for
+users too:
+
+    - hosts: servers
+      roles:
+         - { role: username.rolename, x: 42 }
+
+License
+-------
+
+BSD
+
+Author Information
+------------------
+
+An optional section for the role authors to include contact information, or a website (HTML is not allowed).
