## What it does

The rule covers project layout, Markdown conventions, and documentation checks. It applies to `md` and `mdx` files, recommends keeping `mkdocs.yml` at the project root, and puts source pages in `docs/` with `index.md` as the homepage. Navigation uses `.pages` files and `mkdocs-awesome-pages-plugin` rather than alphabetical ordering.

Pages should have one H1, follow heading levels in sequence, and keep text lines within 80 characters. Use relative paths for internal links, language-labelled fenced blocks for code, and Material for MkDocs admonitions for notes and warnings. For CI, the rule suggests `markdownlint` and `mkdocs-code-validator`; test locally with `mkdocs serve`. An invalid `.pages` file prevents the site from building, so navigation edits need a check.

## Install

### Cursor (native platform)

**Manually: put the files in place**
- File: `.cursor/rules/mkdocs.mdc` — Frontmatter: description, globs, alwaysApply

### Claude Code

**Manually: put the files in place**
- File: `.claude/rules/mkdocs.md` — The paths frontmatter field limits the files: move globs from the source into paths

### Codex

**AGENTS.md**
- Codex reads AGENTS.md: paste the rule text there

### GitHub Copilot

**Manually: put the files in place**
- File: `.github/instructions/mkdocs.instructions.md` — The applyTo field sets which files it applies to: move globs from the source into applyTo

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/rules/mkdocs.md`

### Cline

**Manually: put the files in place**
- File: `.clinerules/mkdocs.md`

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/sanjeed5/awesome-cursor-rules-mdc/tree/HEAD/rules-mdc/mkdocs.mdc

## When to use it
- organize MkDocs pages and define a homepage
- set page order through `.pages` files
- check heading levels and line length
- format links, code blocks, and admonitions consistently
- add Markdown linting and code validation to CI

## Example prompts
- Review the Markdown docs and fix issues covered by the MkDocs rule.
- Set up project navigation with `.pages`, then check it using `mkdocs serve`.
- Check whether CI runs `markdownlint` and `mkdocs-code-validator`.

# mkdocs Best Practices

This guide establishes the definitive standards for writing and maintaining documentation using MkDocs, especially with the Material for MkDocs theme. Adhere to these rules to ensure consistency, readability, and maintainability across all our projects.

## 1. Code Organization & Structure

Always organize your documentation for logical navigation and maintainability.

### 1.1 Root Structure

Place `mkdocs.yml` at the project root, and all Markdown source files within a top-level `docs/` directory. The homepage must be `index.md`.

❌ BAD:
```
my-project/
├── docs/
│   ├── mkdocs.yml  # mkdocs.yml should be at project root
│   └── homepage.md # Homepage should be index.md
```

✅ GOOD:
```
my-project/
├── mkdocs.yml
└── docs/
    ├── index.md
    └── user-guide/
        └── getting-started.md
```

### 1.2 Navigation Ordering

Control navigation explicitly using the `mkdocs-awesome-pages-plugin` and `.pages` files. Never rely on default alphabetical ordering.

❌ BAD:
```
# mkdocs.yml
nav:
  - Home: index.md
  - API: api.md
  - Setup: setup.md # Order is alphabetical, not logical
```

✅ GOOD:
```
# docs/.pages
nav:
  - Home: index.md
  - Setup: setup.md
  - API: api.md
  - ... # Include remaining pages automatically
```

## 2. Markdown Style & Content

Enforce a strict Markdown style for readability and consistency, ideally with `markdownlint`.

### 2.1 Headings Hierarchy

Use a single H1 (`#`) per page for the main title. Subsequent headings must follow a strict, sequential hierarchy (H2, H3, etc.). Never skip heading levels.

❌ BAD:
```markdown
# My Page Title
### A Sub-section # Skipped H2
```

✅ GOOD:
```markdown
# My Page Title
## Introduction
### Key Concepts
```

### 2.2 Line Length

Limit text lines to 80 characters for improved readability and diffs. Exceptions are allowed for long URLs, tables, and code blocks.

❌ BAD:
```markdown
This is a very long line of text that exceeds eighty characters and makes it difficult to read and review, especially in side-by-side diffs.
```

✅ GOOD:
```markdown
This is a standard line of text that adheres to the eighty-character limit.
It improves readability and simplifies code reviews.
```

### 2.3 Fenced Code Blocks

Always use fenced code blocks with language identifiers for syntax highlighting. Never use indented code blocks.

❌ BAD:
```markdown
    This is an indented code block.
    It lacks syntax highlighting and is harder to read.
```

✅ GOOD:
```python
def hello_world():
    print("Hello, MkDocs!")
```

### 2.4 Internal Links

Use relative paths for all internal links to Markdown files. MkDocs automatically converts these to correct HTML paths.

❌ BAD:
```markdown
Please see the [Getting Started](/user-guide/getting-started/) guide. # Absolute path
Please see the [Getting Started](https://example.com/user-guide/getting-started.md) guide. # Full URL
```

✅ GOOD:
```markdown
Please see the [Getting Started](user-guide/getting-started.md) guide. # Relative path
```

### 2.5 External Links & Buttons

Mark external links to open in a new tab using `{target=_blank}`. Use Material for MkDocs button syntax for prominent calls to action.

❌ BAD:
```markdown
[Our GitHub](https://github.com/our-org) # Opens in same tab
<a href="https://github.com/our-org" class="button">GitHub</a> # Raw HTML
```

✅ GOOD:
```markdown
[Our GitHub](https://github.com/our-org){target=_blank}
[Visit Our Blog](https://practical.li/blog){.md-button .md-button-primary target=_blank}
```

### 2.6 Admonitions

Use Material for MkDocs admonitions for notes, warnings, and tips. Never use blockquotes for this purpose.

❌ BAD:
```markdown
> **Warning:** This action is irreversible.
```

✅ GOOD:
```markdown
