 Dependencies:
   - awscli
   - python3-boto3
+
+
+Before running any of the EC2 related playbooks, first create a vars file. Use host_vars/datanommer.yml as a reference.
+When running the playbook add an extra var "-e initiative_name=<vars_file_name>"
+
+i.e. ansible-playbook create_ec2.yml -e "initiative_name=datanommer"
+
+When creating a snapshot a description must be passed as an extra var with the key `snap_description`
+The description should mention why the snaphot was created.
+
+i.e. ansible-playbook snapshot_ebs_volume.yml -e "initiative_name=datanommer" -e "snap_description=database partitioned by year"
