Quick Start

Introduction

Fumadocs is a documentation framework based on Next.js, designed to be fast and flexible. It composes seamlessly into Next.js App Router, and benefits from the React Server Component (RSC) model.

We separated Fumadocs into multiple parts:

Core

The core of Fumadocs. Just like the CPU, it handles most of the logic, including document search, content source adapters, and Markdown/MDX plugins.

UI

The default theme of Fumadocs, it offers a beautiful look for documentation sites and many interactive components.

Content Source

The input/source of your content, it can be a CMS, or local data layers like Content Collections and Fumadocs MDX.

Fumadocs Core will process your content source, hence theoretically any kind of format and source can be supported by Fumadocs.

Use Cases

Documentation

Fumadocs focuses on authoring experience, it provides a beautiful theme and many docs automation tools.

It helps you to iterate your codebase faster while never leaving your docs behind. You can take this site as an example of docs site built with Fumadocs.

Blog sites

Since Next.js is already a powerful framework, most features can be implemented with only Next.js.

Fumadocs Core can process the content (e.g. syntax highlighting), and you can render it with the default theme (Fumadocs UI) or your custom theme. It is particularly helpful if you want to build complicated things like search.

Terminology

For a better understanding of the docs, there are some common terminologies you should know:

Page Tree: A tree of all the pages, separators and folders. It is essential for navigation elements. Types definitions can be found at Page Tree.

MDX File & Page: A MDX file could be located in a folder, or available remotely. Instead, MDX Page is only referring to page.mdx, which is already a page on its own.

You might need to be familiar with Next.js App Router to continue.

Automatic Installation

Create a new app with create-fumadocs-app, it requires Node.js 18+.

npx create-fumadocs-app

It will ask you the following questions:

• Which content source to use? (Recommended: Fumadocs MDX)
• Configure Tailwind CSS?
• Install dependencies?

After that, it will initialize a new fumadocs app. Now you can start hacking!

Enjoy!

Create your first mdx file in the docs folder.

Explore

In the project, you can see:

• app/source.ts: Where you organize code for the source adapter, it is used here to read from your content source.
• app/layout.config.tsx: Shared options for layouts, this is optional but preferred to keep.
• app/(home): The route group for your landing page and other pages.
• app/docs: The entire docs.
• app/api/search/route.ts: The Route Handler for Search.
