+# Footer Slot
+
+### Slot ID: `footer_slot`
+
+## Description
+
+This slot is used to replace/modify/hide the footer.
+
+The implementation of the `FooterSlot` 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.
+
+![Screenshot of Default Footer](./images/default_footer.png)
+
+with a simple custom footer
+
+![Screenshot of Custom Footer](./images/custom_footer.png)

+
+const config = {
+  pluginSlots: {
+    footer_slot: {
+      plugins: [
