-Common Storage for Course
-=========================
+==========================
+Common Storage for Courses
+==========================
 
-It is possible to create a shared storage for a course. With this feature, instructors can add files that will be available across all assignments for all students. 
+Course Shared Storage lets instructors place common files (docs, data sets, starter code, assets) in one location that's available inside every assignment workspace. Read-only files are securely shared and available for all students.
 
+Key Benefits
+------------
+- Single source of truth for course assets
+- No per-assignment re-uploads or duplication
+- Consistent path for code and terminal access
+
+|
+
+====================
+Using Common Storage
+====================
+
+Enable Course Shared Storage
+----------------------------
+
+1. Open the course and go to ``Admin → Course Details``.
+2. Scroll to **Course Shared Storage** and toggle **Shared storage**: **On**.
+3. Click **Save Changes**.
+
+.. image:: /img/enable-shared-storage.png
+   :alt: Toggle to enable Course Shared Storage in Admin → Course Details
+   :width: 80%
+   :align: center
+
+.. note:: Once enabled, you will see the **Storage** tab in the **Admin** area of the course.
+
+Add Folders & Files
+-------------------
+
+1. Navigate to ``Admin → Storage``.
+2. Use **Create Directory** to make a top-level folder (e.g., ``Assignment-1`` or ``Datasets``).
+3. Select a folder, then use **Upload File** to add one or more files.
+4. Repeat for additional assignments or resources as needed.
+
+.. image:: /img/storage-browser.png
+   :alt: Storage browser showing a dataset folder with uploaded files
+   :width: 80%
+   :align: center
+
+.. caution:: You can upload many files, but no single file can be more than 5 GB.
+
+Access Storage From Assignments
+-------------------------------
+
+Inside any assignment workspace, the shared storage appears under the ``storage/`` directory. Students and teachers can read files from there with the terminal, editors, or program code.
