+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+This is the **Plane product documentation site** ([docs.plane.so](https://docs.plane.so)), built with VitePress. It was recently migrated from Docusaurus — the old `sidebars.ts` is a legacy artifact and is no longer used.
+
+## Commands
+
+```bash
+pnpm dev              # Start local dev server
+pnpm build            # Production build (outputs to docs/.vitepress/dist/)
+pnpm preview          # Preview production build locally
+pnpm format           # Format all files with oxfmt
+pnpm format:check     # Validate formatting (runs in CI)
+```
+
+## Architecture
+
+### Directory Layout
+
+- `docs/` — all documentation content as Markdown files
+- `docs/.vitepress/config.mts` — main VitePress config: sidebar navigation, head tags, analytics, theme settings
+- `docs/.vitepress/theme/` — custom theme layer extending VitePress default theme
+- `docs/.vitepress/theme/index.ts` — theme entry: registers custom components and tabs plugin
+- `docs/.vitepress/theme/style.css` — global CSS (Tailwind v4, custom properties, component styles)
+- `docs/.vitepress/theme/components/` — custom Vue components used in Markdown
+- `docs/public/` — static assets (fonts, logos)
+- `vercel.json` — 200+ URL redirects for backward compatibility with old Docusaurus paths
+- `sidebars.ts` — **legacy file from Docusaurus migration, not used by VitePress**
+
+### Sidebar Navigation
+
+The sidebar is defined entirely in `docs/.vitepress/config.mts` under `themeConfig.sidebar`. When adding or reorganizing pages, edit this array directly.
+
+### Custom Vue Components
+
+These are globally registered and can be used directly in any Markdown file:
+
+- **`<Card>`** — content card with optional icon and link. Has built-in SVG icons for GitHub, Slack, GitLab, Sentry, Linear, Asana, Jira, CSV.
+- **`<CardGroup>`** — responsive grid wrapper. Prop: `cols` (default 2).
+- **`<Tags>`** — pricing tier badges (Pro, Business, Enterprise). Accepts `:tags` array with `name`, `link`, and `additionalClass` (`pro`, `business`, `enterprise`).
+
+### Markdown Conventions
+
+```markdown
+<!-- Pricing tags -->
+<Tags :tags='[{ name: "Pro", link: "/url", additionalClass: "pro" }]' />
+
+<!-- Card groups -->
+<CardGroup :cols="2">
+  <Card title="Title" icon="github" href="/path">
+    Description
+  </Card>
+</CardGroup>
+
+<!-- Admonitions -->
+::: tip
+::: warning
+::: danger
+
+<!-- Tabs (via vitepress-plugin-tabs) -->
+:::tabs
+== Tab 1
+Content
+== Tab 2

+
+<!-- Image styling via hash fragments -->
+![Alt](https://url#hero)       <!-- rounded corners + shadow -->
+![Alt](https://url#hero-tl)    <!-- top-left corner only -->
+```
+
+### Image Hosting
+
+All documentation images are hosted externally at `https://media.docs.plane.so/`. Reference them by full URL in Markdown.
+
+## CI
+
+GitHub Actions (`.github/workflows/build.yml`) runs two jobs on PRs and pushes to `master`:
+1. **format** — `pnpm format:check`
+2. **build** — `pnpm build`
+
+## Formatting
+
+Uses oxfmt (`.oxfmtrc.json`): 120 char width, 2-space indent, ES5 trailing commas.
