+* `courseId` - String.
+* `blockId` - String. The usage id of the current unit being viewed / edited.
+* `unitTitle` - String. The name of the current unit being viewed / edited.

+* `readOnly` - Boolean. True if the user should not be able to edit the contents of the unit.
+
+### Description
+
+The slot wraps the sidebar that is displayed on the unit editor page. It can
+be used to add additional sidebar components or modify the existing sidebar.
+
+> [!IMPORTANT]
+> This document describes an older version `v1` of the `CourseAuthoringUnitSidebarSlot`.
+> It is recommended to use the `org.openedx.frontend.authoring.course_unit_sidebar.v2` slot ID for new plugins.
+
+The `v1` slot has the following limitations compared to the `v2` version:
+* It renders conditionally based on the `isUnitVerticalType` prop, which means the plugins won't be rendered in other scenarios like unit with library blocks.
+* It does **not** wrap the `SplitTestSidebarInfo` component. So it can't be hidden from the sidebar by overriding the components in the slot.
+* As it is not the primary child component of the sidebar, CSS styling for inserted components face limitations, such as an inability to be `sticky` or achieve 100% height.
+
+## Example 1
+
+![Screenshot of the unit sidebar surrounded by border](./images/unit_sidebar_with_border.png)
+
+The following example configuration surrounds the sidebar in a border as shown above.
+
+```js
+import { PLUGIN_OPERATIONS } from '@openedx/frontend-plugin-framework';

+          ),
+        },
+      ],
+    },
+  }
+};
+export default config;
+```
+
+## Example 2
+
+![Screenshot of the unit sidebar with an extra component listing all the problem blocks](./images/unit_sidebar_with_problem_blocks_list.png)

+```js
