Quick Start
cd website
npm install # First time only
npm start # Dev server at http://localhost:3000

Writing Documentation
Principles
- User-first: Answer "what can I do?" before "how does it work?"
- Scannable: Use headers, code blocks, tables for keyboard shortcuts
- Progressive disclosure: Quick overview -> detailed usage -> full reference
- Working examples: Every feature needs runnable code, not
...placeholders
Creating a New Doc
Add a Markdown file in website/docs/ with YAML frontmatter:
---
sidebar_position: 2
title: My New Page
---
# My New Page
Content here. Supports **Markdown** and MDX.
Frontmatter options:
sidebar_position: Order in sidebar (lower = higher)sidebar_label: Override sidebar texttitle: Page titledescription: Meta description for SEOslug: Custom URL path
Plugin Documentation Pattern
# Plugin Name
One-line description.

## Overview
Brief explanation of UI layout and core purpose.
## Feature Section
Description with keyboard shortcut table:
| Key | Action |
|-----|--------|
| `s` | Stage file |
| `d` | View diff |
## Navigation
How to move around.
## Command Reference
Complete shortcut list by context.
Organizing Docs in Folders
docs/
├── intro.md
├── guides/
│ ├── _category_.json # Folder metadata
│ ├── installation.md
│ └── configuration.md
_category_.json controls folder appearance:
{
"label": "Guides",
"position": 2,
"collapsible": true,
"collapsed": false
}
Sidebar Configuration
Auto-generates from docs/ folder structure. To customize, edit sidebars.js:
const sidebars = {
tutorialSidebar: [
'intro',
{
type: 'category',
label: 'Guides',
items: ['guides/installation', 'guides/usage'],
},
],
};
Using MDX
Docs support MDX (Markdown + JSX):
import Tabs from '@theme/Tabs';
import TabItem from '@theme/TabItem';
<Tabs>
<TabItem value="npm">npm install</TabItem>
<TabItem value="yarn">yarn add</TabItem>
</Tabs>
Front Page
The front page is at website/src/pages/index.js -- a React component using Docusaurus Layout and theming.
export default function Home() {
return (
<Layout title="Home" description="...">
<HomepageHeader />
<main className="container">
{/* Add content here */}
</main>
</Layout>
);
}
Styling: index.module.css for page-specific, src/css/custom.css for global overrides.
Images and Screenshots
Website doc screenshots (for pages in website/docs/):
- Store in:
docs/screenshots/(project root) - Reference:

README / repo doc screenshots:
- Store in:
docs/screenshots/(project root) - Reference:
(from repo root)
General website images (logos, icons):
- Store in:
website/static/img/ - Reference:

In JSX:
import screenshot from '@site/static/img/logo.png';
<img src={screenshot} alt="Logo" />
Blog Posts
Date-prefixed Markdown files in blog/:
---
slug: my-post
title: Post Title
authors: [default]
tags: [announcement, release]

Style Guidelines
No Emoji Policy
Never use emoji in site content, components, or documentation. Use Lucide icons instead.
Icons (Lucide)
The site uses Lucide icon font (CDN import in docusaurus.config.js).
<i className="icon-terminal" />
<i className="icon-check" />
<i className="icon-git-branch" />
Common icons: icon-eye, icon-terminal, icon-rocket, icon-check, icon-copy, icon-external-link, icon-git-branch, icon-zap, icon-keyboard, icon-layers, icon-code.
Browse all: https://lucide.dev/icons
Terminal Aesthetic
- Monospace fonts (
JetBrains Mono,Google Sans Code) - Dark backgrounds with muted colors
- Bright accents from Monokai palette (green, blue, pink, yellow)
- Clean 1px borders, subtle gradients and glows
Building and Deploying
cd website
npm run build # Outputs to website/build/
npm run serve # Preview built site locally
Deploys automatically via GitHub Actions when changes to website/ merge to main.
.github/workflows/deploy-docs.yml-- Deploys to GitHub Pages.github/workflows/test-docs.yml-- Validates PR builds- Live site: https://marcus.github.io/sidecar
Common Tasks
| Task | Steps |
|---|---|
| Add docs section | Create folder in website/docs/, add _category_.json, add Markdown files |
| Change theme colors | Edit src/css/custom.css (:root and [data-theme='dark'] variables) |
| Add custom component | Create in src/components/MyComponent/index.js, import with @site/src/components/MyComponent |
Troubleshooting
- Build fails with broken links: Config uses
onBrokenLinks: 'throw'. Temporarily change to'warn'for local dev. - Styles not updating:
npm run clear && npm start - GitHub Pages 404: Verify
baseUrlmatches repo name (/sidecar/).
