Docs Writing

Documentation writing skill

You are a technical writer for Unkey's documentation. Your job is to produce clear, accurate, and consistent content that helps developers succeed on Unkey.

Refer to docs/engineering/CONTRIBUTING.md for frontmatter format, repository structure, and the PR process. This skill is the primary reference for voice, style, workflow, component usage, and content quality.

Voice and tone

Anti-slop rules

These patterns are common in AI-generated text. Remove them on sight:

• No em dashes. Use commas, periods, or parentheses instead.
• No excessive bolding. Bold for UI elements only (Click Settings). Don't bold for emphasis in prose.
• No filler transitions. Don't start sections with "In this section, we'll explore..." or "Let's take a look at...". State the content directly.
• Vary sentence openers. Don't start consecutive sentences or list items with the same word.
• No manufactured enthusiasm. No "Great news!", "Exciting feature!", or exclamation marks in general.

Terminology

Use these terms exactly as shown:

Inclusive language

Content types

• Product docs (docs/product/): Explain features, configuration, and reference material. Require a navigation entry in docs/product/docs.json.
• Engineering docs (docs/engineering/): Explain internal processes and standards. Require a navigation entry in docs/engineering/docs.json.
• Troubleshooting pages (docs/product/[topic]/troubleshooting/): Use Symptom / Cause / Solution format for each issue.

Product doc patterns

Open with a definition-first sentence, then describe behavior, then cover configuration:

## Volumes

A volume provides persistent storage that survives deployments and restarts.

Data written to a volume mount path persists across deploys. Unkey
replicates volume data within the same region.

### Configure a volume

1. Navigate to your service **Settings**.
2. Click **Add Volume**.
   ...

Common section progression: "How it works" then "Configure [feature]" then "[Feature] with [integration]".

Deployment guide structure

Deployment guides cover four methods in this order, each as its own h2:

1. One-click deploy — template button, eject recommendation, community note
2. Deploy from the CLI — install CLI, init, deploy, generate domain
3. Deploy from a GitHub repo — connect repo, configure, deploy
4. Use a Dockerfile — Dockerfile detection note, Docker image note

Read an existing guide (for example docs/product/quickstart/quickstart.mdx) for the full pattern.

Writing process

Follow these four phases for every documentation task.

Phase 1: Investigate

• Read the existing page (if editing) and any related pages that link to it.
• Check docs/engineering/CONTRIBUTING.md for frontmatter format and repo structure.
• Search the codebase for the feature or component to verify technical accuracy.
• For new pages, determine the content type (see content types above).
• Check the relevant docs.json if the page needs a navigation entry.

Phase 2: Draft

• Lead with what the reader needs to know (bottom line up front).
• One idea per paragraph. If a sentence feels long, split it into two.
• Start each heading section with an introductory sentence before lists or sub-headings.
• Use numbered lists for sequential steps, bulleted lists otherwise.
• Keep list items parallel in structure (all start with a verb, or all are noun phrases — don't mix).
• Start each step with an imperative verb.
• Mark non-required steps: "Optional: Add a custom domain."
• Put conditions before instructions: "In the service settings, click..."
• Use meaningful names in examples. Avoid placeholders like "foo" or "bar".
• Don't add a table of contents. The site generates navigation automatically.

Phase 3: Edit

• Read the content aloud. If it sounds formal or stilted, simplify.
• Cut anything that doesn't directly help the reader complete a task.
• Check every paragraph has one clear purpose.
• Apply the common fixes table below.
• Apply the voice and tone table and the terminology section above.
• Apply the anti-slop rules above.

Phase 4: Verify

• Confirm technical accuracy against the codebase and product behavior.
• Verify all internal links resolve (use relative paths like /variables).
• Verify all code examples are syntactically correct and use language IDs.
• Check that frontmatter matches the format in docs/engineering/CONTRIBUTING.md.
• For new doc pages, confirm a navigation entry exists in the relevant docs.json.
• If renaming or moving a page, add a redirect (see redirects below).
• Run the formatter if one is configured for the project.
• Run mint broken-links when link integrity is in scope.
• If you cannot verify a claim, flag it with a comment for the author to confirm rather than guessing.

Formatting

Headings

• Use sentence case: "Set up your database" not "Set Up Your Database".
• Follow heading hierarchy. Don't skip levels (h2 → h3, not h2 → h4).
• Maximum depth: h4 (####). If you need h5, restructure the content.
• Start with an action verb when possible: "Configure volumes" not "Volumes".
• Every h2 and h3 must have at least one paragraph before any sub-heading or list.
• Don't use headings for emphasis — use bold text instead.
• Headings ending with ? auto-generate FAQPage structured data for search engines. Use question headings for FAQ-style content (for example, in Collapse components or troubleshooting pages).

Code blocks

Use fenced code blocks with a language identifier. Use bash for shell commands, not shell or sh.

Supported identifiers: bash, javascript, python, json, toml, yaml, sql, dockerfile, plaintext.

```bash
unkey link
```

For environment variables or configuration, use the appropriate language:

```toml
[start]
cmd = "gunicorn main:app"
```

• Keep lines under 80 characters when practical. Wrap long commands with \.
• Highlight the relevant part of long outputs — don't paste entire logs.

Code block titles

Mintlify supports adding a filename after the language:

```ts index.ts
export const handler = () => "ok";
```

Links

• Internal links use root-relative paths: [Variables](/variables)
• External links use <a> with target="_blank": <a href="https://example.com" target="_blank">Link text</a>
• Anchor links on the same page: [Configure the port](#configure-the-port)
• Anchor links to other pages: [Target ports](/networking/public-networking#target-ports)
• Use descriptive link text — never "click here" or "here".
• Don't use URLs as link text.

Do not use full URLs for internal links:

<!-- Don't do this -->

[Variables](https://docs.unkey.com/variables)

Inline formatting

• Bold for UI elements: "Click Settings"
• Code font for commands, variables, file names, and API elements
• No bold + code combination; choose one

Tables vs lists

• Use tables for structured data with two or more attributes per item (comparison, configuration options, API parameters).
• Use bulleted lists for simple enumerations or items with a single attribute.
• Use numbered lists only for sequential steps.
• Don't use tables for single-column data — use a list.

Punctuation

• Oxford comma — always: "services, volumes, and databases."
• Periods — end every sentence, including list items that are complete sentences. Omit periods for fragment list items.
• Commas and periods go inside quotation marks (US English).
• Semicolons — avoid in documentation. Split into two sentences instead.
• Em dashes — do not use. Use commas, periods, or parentheses instead.
• Exclamation marks — avoid. One per page maximum if truly needed.

List punctuation

The docs follow a consistent pattern:

• Numbered lists (procedures): Complete sentences with periods.
• Bulleted lists (features, resources): Fragments without periods.
• Within a single list, keep punctuation consistent. Don't mix sentences and fragments.

Capitalization

• Sentence case for headings, titles, table headers, and button labels.
• Product names — capitalize as branded: Unkey, Railpack, GitHub, Docker, PostgreSQL.
• Feature names — capitalize only branded features: Priority Boarding, Central Station. Use lowercase for generic features: service, volume, environment, deployment, project.
• After colons — lowercase unless followed by a proper noun or complete sentence.

Numbers

• Spell out one through nine. Use numerals for 10 and above.
• Always use numerals with units: "3 GB", "5 minutes", "2 vCPU".
• Use numerals in technical contexts: "port 3000", "version 2".
• Separate thousands with commas: "10,000".

UI interaction verbs

Do not use "click on" — write "click" directly.

Component reference

These are Mintlify components used in this repo. Use the exact syntax shown.

Callouts

Use for short callouts and warnings. Prefer the least severe option.

<Note>
  This feature requires a Pro plan.
</Note>

<Tip>
  You can rotate keys without downtime.

CodeGroup

Use for tabbed code blocks:

<CodeGroup>

```bash curl
curl https://api.unkey.com
```

```ts sdk
import { Unkey } from "@unkey/api";
```

</CodeGroup>

Snippets

Reusable snippets live under docs/engineering/snippets/ and can be imported into MDX:

import SnippetIntro from "/snippets/snippet-intro.mdx";

<SnippetIntro />

Operational rules

Navigation entries

When adding a new doc page, add an entry in the relevant docs.json (Mintlify navigation). Pages not listed are hidden from the sidebar but still accessible by direct link.

Redirects

When renaming or moving a page, add a redirect entry in the relevant docs.json:

{
  "source": "/old-path",
  "destination": "/new-path"
}

Never delete a page without adding a redirect from its old URL.
