     - To launch the virtual machine instances, run:
 
     ```bash
-    make launch
+    $ make launch
     ```
 
     - To clean up all instances and buckets, run:
 
     ```bash
-    make clean

     - To delete machines and buckets and then relaunch, run:
 
     ```bash
-    make reset

+
+    b. **Using `cloudy.py`**
+
+    You can also use the `cloudy.py` script for the same purpose:
+
+    ```bash
+    $ ./cloudy.py launch

+    $ ./cloudy.py reset
     ```
