## Example Usage
Tell the AI agent of your choice:
> Open Chrome, go to github.com/angiejones, and take a screenshot.
The agent will call Selenium's APIs to `start_browser`, `navigate`, and `take_screenshot`. No manual scripting or explicit directions needed.
## Supported Browsers
Chrome, Firefox, Edge, and Safari.
> **Safari note:** Requires macOS. Run `sudo safaridriver --enable` once and enable
> "Allow Remote Automation" in Safari → Settings → Developer. No headless mode.
