Documentation Guidelines

Standards for writing and maintaining Hyperframes documentation. Based on patterns from Remotion, Stripe, Tailwind CSS, and Astro.

Core Principles

1. One-sentence intro rule — Every page opens with a single sentence telling the reader what this page helps them do or understand. No preamble, no history.

2. Outcome before implementation — Show what the code produces (rendered result, terminal output, file structure) before showing the code itself.

3. Show, don't tell — Use concrete examples with realistic values. Never use foo/bar/baz. Prefer a working HTML snippet over a description of what to write.

4. Two content modes — Guides build narratives with progressive complexity. References enable scanning with standardized structure. Never mix them.

5. No dead ends — Every page links forward (next steps), backward (prerequisites), and sideways (related concepts). Readers should never reach a page with nowhere to go.

Writing Style

• Second person, active voice, imperative mood: "Use X to do Y." Not "The developer should consider using X."
• Present tense: "The runtime manages media playback." Not "The runtime will manage..."
• Be direct: "This breaks rendering." Not "This may potentially cause issues with the rendering pipeline."
• Prerequisites at point of need: State requirements where they matter, not in a wall at the top.
• Conversational but precise: Friendly tone, exact technical details.

Code Examples

Always annotate code blocks

```html index.html
<div data-composition-id="root" ...>
```​

The filename after the language tag tells readers where the code goes.

Use numbered comments for multi-step code

// 1. Create a paused timeline
const tl = gsap.timeline({ paused: true });

// 2. Add animations
tl.from("#title", { opacity: 0, y: -50, duration: 1 }, 0);

// 3. Register the timeline
window.__timelines["my-video"] = tl;

Show expected output

After CLI commands, show what the user should see:

npx hyperframes preview
# ✓ Server running at http://localhost:3000
# ✓ Watching for changes...

Use CodeGroup for multi-platform commands

<CodeGroup>
```bash macOS
brew install ffmpeg
```​
```bash Ubuntu
sudo apt install ffmpeg
```​
</CodeGroup>

Mintlify Components — When to Use

Component	Use When
<Steps>	Sequential setup or tutorial instructions
<CodeGroup>	Same action across platforms/languages
<Tabs>	Alternative approaches with equal weight
<Card> / <Columns>	Navigation to related pages, next steps
<Accordion>	FAQ or optional detail that would bloat the page
<Note>	Non-obvious behavior the reader should know
<Warning>	Something that will break if ignored
<Tip>	Helpful shortcut or best practice
<Info>	Context that aids understanding
<Tree>	File/directory structure
<Frame>	Screenshots or diagrams with captions

Callout budget: max 2-3 per page

More than 3 callouts creates alert fatigue and readers skip them all. Reserve <Warning> for things that genuinely break. Use inline prose for tips.

Cross-Linking

• Link at the point of curiosity: When you mention a concept that has its own page, link it immediately. Don't hoard links.
• "See also" at page bottom: Only for genuinely related content that doesn't fit inline.
• Next steps cards: End guide pages with <Card> links to logical next pages.

File Conventions

• All doc pages are .mdx (not .md)
• Use kebab-case for filenames: frame-adapters.mdx, not frameAdapters.mdx
• Frontmatter requires title and description
• Description should be under 160 characters (used for SEO/social)

Maintenance

• Docs live in the repo at /docs and deploy automatically on merge to main
• PRs that change user-facing behavior should update relevant doc pages
• Run mint validate and mint broken-links before pushing doc changes
