# MkDocs — Project Documentation with Markdown

> MkDocs turns a folder of Markdown files into a fast static documentation site. With themes like Material for MkDocs, plugins, and search built in, it is the go-to choice for technical docs that need to stay close to the code.

## Install

Save in your project root:

# MkDocs — Project Documentation with Markdown

## Quick Use
```bash
pip install mkdocs mkdocs-material
mkdocs new mydocs
cd mydocs
mkdocs serve       # http://127.0.0.1:8000 with live reload
mkdocs build       # static site in ./site
mkdocs gh-deploy   # push to gh-pages branch
```

## Introduction
MkDocs is the most popular static site generator specifically built for project documentation. Unlike generic SSGs (Hugo, Jekyll), it ships with docs-focused features out of the box: navigation YAML, search, doc-site themes, and a rich plugin ecosystem. The Material for MkDocs theme is so widely used it powers the docs for FastAPI, Pydantic, DVC, and thousands more.

With over 20,000 GitHub stars (plus 21,000 for Material), MkDocs is the default for Python-adjacent projects and a safe choice for any technical team that writes Markdown.

## What MkDocs Does
MkDocs reads a `mkdocs.yml` config, converts your `docs/` folder of Markdown into a static HTML site, and serves it with a dev server or builds to `./site`. Themes, plugins, and Markdown extensions cover navigation, search, versioning, API reference generation, and diagrams.

## FAQ
**Q: MkDocs vs Docusaurus?**
A: MkDocs is simpler and Markdown-only — great for small/medium projects. Docusaurus uses MDX (Markdown + React) and fits teams that want interactive docs. Both produce beautiful sites; pick by team preference.

**Q: How do I version docs?**
A: Install `mike` (`pip install mike`) and deploy with `mike deploy 1.0 latest --push`. You get a version selector in Material theme automatically.

**Q: Can I auto-generate API reference from Python docstrings?**
A: Yes. `mkdocstrings` pulls docstrings and types, rendering them in Material style. It reads Google, NumPy, and Sphinx-style docstrings.

**Q: Is MkDocs limited to Python projects?**
A: Not at all. MkDocs is written in Python but the output is generic Markdown → HTML. It is used for projects in Go, Rust, JS, and non-code teams.
