+# AuthoringAppSlot
+
+### Slot ID: `authoring_app_slot`
+
+### Plugin Props:
+
+NONE
+
+## Description
+
+The slot wraps the entire application. It can be used to add content before or
+after the application (such as cookie banners) or to wrap the entire
+application in a component. One possible use case of that is to wrap the entire
+application in a context manager that would allow communication between
+different slots injected on the page.
+
+## Example
+
+![Screenshot of the entire app surrounded by border](./images/app_wrapped_in_border.png)
+
+The following example configuration wraps the entire app in a dashed border as
+shown above.
+
+```js
+import { PLUGIN_OPERATIONS } from '@openedx/frontend-plugin-framework';
+
+const config = {
+  pluginSlots: {
+    authoring_app_slot: {
+      keepDefault: true,
+      plugins: [
+        {
+          op: PLUGIN_OPERATIONS.Wrap,
+          widgetId: 'default_contents',
+          wrapper: ({ component }) => (
+            <div style={{ border: 'thick dashed red' }}>{component}</div>
+          ),
+        },
+      ],
+    },
+  }
+};
+export default config;
+```
