Markdown Style Guide

Apply the Markdown conventions from ./references/MARKDOWN.md when creating or editing Markdown files. This guide targets GitHub Flavored Markdown (GFM) and aligns with markdownlint-cli2 rules.

Common Mistakes

These two issues cause the most lint failures. Check every Markdown file for them.

Tables: align all pipes vertically

<!-- Correct: pipes aligned, cells padded -->

| Name    | Type   | Default |
| ------- | ------ | ------- |
| timeout | number | 30      |
| retries | number | 3       |

<!-- Wrong: ragged pipes, no padding -->

| Name | Type | Default |
| --- | --- | --- |
| timeout | number | 30 |
| retries | number | 3 |

Procedure: write all rows, find the longest content per column, pad every cell to that width, fill delimiter hyphens to match, then verify all pipes line up.

Code blocks: always include a language identifier

<!-- Correct -->

```bash
echo "hello"
```

<!-- Wrong: bare fence -->

```
echo "hello"
```

Use text when no syntax highlighting applies. Never leave the opening fence bare.

Key Conventions

Read ./references/MARKDOWN.md for the complete guide. Summary:

Document Structure

• One top-level heading (# Title) per document (MD025)
• Blank line before and after headings, lists, code blocks, and block quotes
• End files with a single trailing newline (MD047)

Headings

• ATX-style headings (#) only, never Setext underlines (MD003)
• Do not skip heading levels (MD001)
• No trailing punctuation on headings (MD026)
• Sibling headings must be unique; same text is fine under different parents (MD024)

Links and Images

• Inline links for one-off references: [text](url)
• Reference links for repeated URLs or long URLs: [text][id]
• Always include alt text on images (MD045)

Lists

• Consistent markers: - for unordered (MD004); for ordered lists, use either 1. for every item or sequential numbering (1., 2., 3.), but be consistent within each list (MD029)
• Indent nested lists consistently
• Blank line before and after a list block (MD032)

Tables

• Pad every cell so all pipe characters align vertically; pad delimiter hyphens to match (MD060)
• Leading and trailing pipes on every row (MD055)
• Consistent column count across all rows (MD056)

Code

• Fenced code blocks must have a language identifier, use text if none applies (MD040)
• Backtick fences, not tilde fences (MD048)
• Inline code for identifiers, commands, and short expressions

HTML

• Prefer Markdown syntax when an equivalent exists
• HTML is acceptable for features Markdown lacks (<details>, <kbd>, <br>, <sub>, <sup>, etc.)

Validation

After creating or editing Markdown files, run the project's lint-fix command to auto-correct table alignment, list numbering, and other formatting issues. This is a required final step, not optional.

Check package.json for project-specific scripts (e.g., yarn lint:fix, yarn lint:md:fix, npm run lint:fix). Also check Makefile targets and scripts in bin/. Run the linter in fix mode so it corrects what it can automatically.

If no project-specific lint script is available, use markdownlint-cli2 directly as a fallback.
