+# Studio Footer Slot
+
+### Slot ID: `studio_footer_slot`
+
+## Description
+
+This slot is used to replace/modify/hide the footer.
+
+The implementation of the `StudioFooterSlot` component lives in [the `frontend-slot-footer` repository](https://github.com/openedx/frontend-slot-footer/).
+
+## Example
+
+The following `env.config.jsx` will replace the default footer.
+
