# Headless CMS Playbook | Rangle.io We created this e-book as a comprehensive guide to all things headless. A CMS is only one part of a headless platform. Successfully building and implementing a headless platform requires an architectural plan that aligns with your business objectives. Our guide covers best practices for architecting and implementing your CMS, tech stack, and content workflows. We hope you enjoy our playbook. Do you have any questions we didn't get to?
