The document provides a step-by-step guide for creating or modifying virtual system patterns using IBM Cloud Orchestrator v2.5. It outlines two main steps: 1) Log in as an admin user, create a new template, add images, policies and attributes to the pattern and save changes. 2) Add databases as primary and standby, modify attributes, select OpenStack flavors, and add references with data source details. The goal is to demonstrate how to build new patterns or modify existing ones through the pattern builder tool in IBM Cloud Orchestrator.
