+
+## Dependencies
+
+| Dependency | Install Command |
+| --- | --- |
+| `browser-use` ≥ 0.1.40 | `pip install browser-use` |
+| `markdownify` | `pip install markdownify` |
+| `playwright` + chromium | `pip install playwright && playwright install chromium` |
+
+## Use Cases
+
+- Access specific URLs to get page content
+- Interact with web page elements (click, type, etc.)
+- Verify deployed web pages

+<Note>
