Template Features

What's in the Box?

Don't start from scratch. Chapter Zero ships with the exact architecture used to power full-scale technical guides.

  • The Guide System

    Ordered Markdown chapters with a built-in left sidebar navigation, chapter indexes, and a seamless "next chapter" flow.

  • Data-Driven Landing Page

    A high-converting layout featuring a centered hero, audience cards, testimonials, and author bios, all driven simply by YAML data.

  • Automated Social Previews

    Dynamically generates 1200×630 OG image PNGs at build time for every chapter and post.

  • Built-in Marketing & Conversion

    Drop-in components for ConvertKit newsletter signups, contact forms, and support banners.

  • Integrated Blog

    A dated posts collection with index and post layouts for updates that don't fit into the main guide.

  • Deploy Anywhere

    Plain Bridgetown output with a Netlify config included. Deploy wherever static files work.
