+## Website & Documentation System
+
+The official documentation site (https://seatunnel.apache.org) is managed through the `apache/seatunnel-website` repository, built with **Docusaurus 2.4.3**.
+
+### How Documentation Works
+
+Documentation content lives in the **main codebase** (`apache/seatunnel` repo, `docs/` directory). The website repo fetches docs via `npm run sync` (or `tools/build-docs.js`) before building.
+
+The sync process:
+1. Creates `swap/` directory, clones `apache/seatunnel` codebase
+2. Copies `docs/en` to website's `docs/` directory
+3. Copies `docs/zh` to `i18n/zh-CN/` for Chinese translations
+4. Copies `docs/images` to `static/image_en` and `static/image_zh`
+5. Copies `docs/sidebars.js` to root level
+

+### Documentation Categories (per version)
+
+Each version's docs contain:
+- `about.md` - Project overview
+- `command/` - CLI commands (e.g., connector-check)
+- `concept/` - Core concepts (config, schema-evolution, speed-limit, SQL config, event-listener)
+- `connector-v2/` - Connector documentation
+  - `source/` - Source connector docs (100+ connectors)
+  - `sink/` - Sink connector docs
+  - `changelog/` - Per-connector changelogs
+  - `formats/` - Data formats (Avro, Canal JSON, Debezium JSON, OGG JSON, Protobuf)
+- `contribution/` - Contributor guides
+- `faq.md` - Frequently asked questions
+- `other-engine/` - Flink/Spark engine specifics
+- `seatunnel-engine/` - Zeta engine docs + telemetry
+- `start-v2/` - Getting started guides
+  - `docker/` - Docker deployment
+  - `kubernetes/` - K8s deployment
+  - `locally/` - Local setup
+- `transform-v2/` - Transform documentation (SQL, etc.)
+
+### Versioned Documentation
+
+20 historical versions maintained: `1.x`, `2.1.0`~`2.1.3`, `2.2.0-beta`, `2.3.0-beta`~`2.3.12`
+
+Total: ~3691 versioned doc files + ~1652 i18n files
+
+### Website Development
+
+```bash
+# Clone
+git clone git@github.com:apache/seatunnel-website.git
+cd seatunnel-website
+
+# Sync docs from main repo
+npm run sync
+# Or with SSH: export PROTOCOL_MODE=ssh && npm run sync
+
+# Install dependencies
+npm install
+
+# Dev server (English)
+npm run start
+
+# Dev server (Chinese)
+npm run start-zh
+
+# Production build (needs ~10GB heap)
+npm run build
+# Or faster parallel build
+npm run build:fast
+
+# Serve built site
+npm run serve
+```
+
+### Adding a New Version
+
+```bash
+# 1. Create versioned snapshot
+npm run version <target_version>
+
+# 2. Update download links
+# Edit src/pages/download/st_data.json
+```
+
+### Branching Strategy
+
+| Branch | Purpose |
+|---|---|
+| `main` | Default development branch |
+| `asf-site` | Production (https://seatunnel.apache.org) |
+| `asf-staging` | Staging (https://seatunnel.staged.apache.org) |
+
+### CI/CD
+
+GitHub Actions workflow (`.github/workflows/deploy.yml`):
+- Triggers: push to `main`, PRs to `main`, daily cron (5:00 AM UTC)
+- Node.js 18.20.7
+- Steps: `npm install` -> `npm run sync` -> `npm run build` -> deploy to `asf-site` branch
+
+### Key Conventions
+
+- Directory names: lowercase, underscore-separated, plural (e.g., `scripts`, `components`)
+- JS/static files: lowercase, dash-separated (e.g., `render-dom.js`)
+- Images: stored under `static/{module_name}`
+- Styles: placed in `src/css/`
+- Most pages have "Edit this page" link pointing to GitHub source
