+## Shadow DOM support / Shadow-root interaction
+
+🔵 SeleniumBase lets you pierce through open Shadow DOM selectors (to interact with elements inside) by adding ``::shadow`` to CSS fragments that include a shadow-root element. For multi-layered shadow-roots, you must individually pierce through each shadow-root element that you want to get through.
+
+🔵 Here are some examples of Shadow DOM selectors:
+
+```python
+css_1 = "downloads-manager::shadow #no-downloads"
+
+css_2 = "downloads-manager::shadow #downloadsList downloads-item::shadow #file-link"
+
+css_3 = "downloads-manager::shadow downloads-toolbar::shadow cr-toolbar::shadow cr-toolbar-search-field::shadow cr-icon-button"
+
+css_4 = "downloads-manager::shadow downloads-toolbar::shadow cr-toolbar::shadow cr-toolbar-search-field::shadow #searchInput"
+
+css_5 = "downloads-manager::shadow downloads-toolbar::shadow cr-toolbar::shadow cr-toolbar-search-field::shadow #clearSearch"
+```
+
+🔵 The shadow-root (``::shadow``) elements are transitional, and therefore cannot be the final part of your CSS selectors. Complete your CSS selectors by including an element that's inside a shadow-root.
+
+🔵 Note that ``::shadow`` selectors only exist within SeleniumBase, and do not exist outside of it.
+
+🔵 Here's an example test that interacts with Shadow DOM elements: [examples/test_shadow_dom.py](https://github.com/seleniumbase/SeleniumBase/blob/master/examples/test_shadow_dom.py)
