Core Concepts

Edition

Learn how to write your documentation.

Docus provides customization options to suit your needs.

  • You can integrate it as a complete website solution with both landing and documentation sections
  • Or embed the documentation functionality within your Nuxt application while maintaining full control over all other aspects (thanks to the Nuxt layer feature).

Landing page

The landing page is the first page your visitors see at the root / of your site.

Markdown (default)

By default, the landing page corresponds to the content/index.md file.

Docus automatically:

  • Creates a landing content collection for the content/index.md file
  • Registers the / route to render your Markdown landing page
The MDC syntax gives you the ability to use Vue components, including slots and props in your .md files. You can use any Nuxt UI component in your Markdown to build your landing page.

Vue (custom)

Since Docus is a layer, it allows you to fully customize your landing page by creating a Vue page at app/pages/index.vue. This gives you full control with Vue components, custom layouts, and advanced interactions.

In this case, Docus:

  • Do not create landing collection
  • Use native Nuxt router and consider index.vue as your home page
This automatic detection works for both single-language and multi-language (i18n) setups.

Components

MDC provides a dedicated syntax to easily use Vue components in your content:

content/index.md
:::u-page-feature
:::

Slots

Slots can receive text content or other components.

  • Default slot is rendered directly inside the component or with #default.
  • Named slots are defined using the # symbol followed by the slot name.
index.md
:::u-page-feature
  #title
  Nuxt 4
  
  #description
  Powered by Nuxt 4 for optimal performances and SEO.
:::

Props

Props are passed using inline syntax or YAML frontmatter within the component block:

index.md
:::u-page-feature{icon="i-simple-icons-nuxt" to="https://nuxt.com"}
  #title
  Nuxt 4
  
  #description
  Powered by Nuxt 4 for optimal performances and SEO.

Documentation pages

There is a one to one relationship between content files and pages on your site. Each Markdown page in the content/ folder maps directly to a page route.

Without docs folder

To get started, simply edit or add a .md files in the content/ directory to have your pages updated. Docus will handle routing, navigation, and full-text search automatically.

content/
├── index.md              # Landing page → /
├── getting-started.md    # Documentation → /getting-started
└── guide/
    └── introduction.md   # Documentation → /guide/introduction

With docs folder

You can optionally organize your documentation files within a docs/ subfolder. When Docus detects a docs/ folder in your content/ directory, it automatically prefixes all documentation URLs with /docs.

content/
├── index.md                  # Landing page → /
└── docs/
    ├── getting-started.md    # Documentation → /docs/getting-started
    └── guide/
        └── introduction.md   # Documentation → /docs/guide/introduction
This is particularly useful when you want to use Docus as embedded documentation alongside other custom pages. You can create additional pages like a blog, contact page, pricing page, or any other custom content at the root level, while keeping your documentation organized under /docs.

Mixed content

Since Docus is a Nuxt layer, you can combine Markdown files with custom Vue pages:

├── app/
   └── pages/
       ├── pricing.vue       # Custom pricing page → /pricing
       └── contact.vue       # Custom contact page → /contact
└── content/
    ├── index.md              # Landing page → /
    └── blog.md               # Blog page → /blog
    └── docs/                 # Documentation → /docs/*
        ├── getting-started.md
        └── api/
            └── reference.md

This structure gives you the flexibility to build a complete website with Docus. Use Markdown for documentation and Vue pages for custom functionality like blogs, dashboards, or any interactive pages.

Frontmatter

Every file of the content/ folder starts with the --- syntax on top of the page. It corresponds to the frontmatter of your file which is a convention of Markdown-based CMS to provide meta-data to pages.

content/getting-started/edition.md
---
title: 'Edition'
description: 'Learn how to write your documentation.'
---

<!-- Content of the page in pure Markdown -->

Parameters

Pages in the /content directory are defined as page type in Nuxt Content. They all follow the same structure with existing frontmatter keys:
