+        - The exercise panel has two main sections:
+          - **Definitions**: This section handles definitions. You can upload, remove, and manage instructor access to them.
+          - **Exercises**: This section handles exercises. You can create, pause, remove exercises, add participants, and download logs.
+
+    2. **Upload an Exercise Definition**
+    
+        - In the `Definitions` section, click the `+ Add` button to upload a definition.
+        - You may use the showcase definition provided here:

+
+    3. **Create an Exercise**
+        - In the `Exercises` section, click the `+ Add` button.

+
+    4. **Add Participants**
+        - After creating the exercise, click on the `Participants` tab under the exercise you have created.

+
+    5. **Start the Exercise**
+        - Once all configurations and settings are completed, click the `Start` button under the exercise you created.
