-To extend with your own script:
+### CDP server mode
+
+Start a persistent stealth browser and connect to it remotely via Chrome DevTools Protocol:
+
+```bash
+docker run -d --name cloak -p 127.0.0.1:9222:9222 cloakhq/cloakbrowser cloakserve
+```
+
+Then connect from your host machine:
+
+```python
+from playwright.sync_api import sync_playwright
+
+pw = sync_playwright().start()
+browser = pw.chromium.connect_over_cdp("http://localhost:9222")
+page = browser.new_page()
+page.goto("https://example.com")
+print(page.title())
+browser.close()
+```
+
+Pass extra flags to the browser:
+
+```bash
+# With proxy
+docker run -d --name cloak -p 127.0.0.1:9222:9222 cloakhq/cloakbrowser \
+  cloakserve --proxy-server=http://proxy:8080
+
+# Headed mode (renders to Xvfb inside container)
+docker run -d --name cloak -p 127.0.0.1:9222:9222 cloakhq/cloakbrowser \
+  cloakserve --headless=false
+```
+
+Stop the server:
+
+```bash
+docker stop cloak && docker rm cloak
+```
+
+> **Security:** CDP gives full control over the browser (execute JS, read pages, access files).
+> The examples bind to `127.0.0.1` so only your machine can connect. Never expose port 9222
+> to the public internet without additional authentication.
+
+### Docker Compose
+
+```yaml
+services:
+  cloakbrowser:
+    image: cloakhq/cloakbrowser
+    command: cloakserve
+    restart: unless-stopped
+    ports:
+      - "127.0.0.1:9222:9222"
+    healthcheck:
+      test: ["CMD", "curl", "-f", "http://localhost:9222/json/version"]
+      interval: 30s
+      timeout: 5s
+      retries: 3
+      start_period: 10s
+```
+
+Run multiple instances with different fingerprint seeds on different ports — each gets unique canvas noise, client rects, and other browser signals. Pass `--fingerprint=<seed>` in the command (e.g., `cloakserve --fingerprint=12345`).
+
+**Persistent profiles** — mount a volume to keep cookies and sessions across container restarts:
+
+```bash
+docker run --rm -v ./my-profile:/profile cloakhq/cloakbrowser python -c "
+from cloakbrowser import launch_persistent_context
+ctx = launch_persistent_context('/profile')
+page = ctx.new_page()
+page.goto('https://example.com')
+ctx.close()
+"
+```
+
+Run again with the same volume — cookies, localStorage, and cache are restored automatically.
+
+**Resource usage:** ~190MB RAM idle, ~280MB with 3 tabs. ~30MB per additional tab.
