 This script will generate the Debian package files and place them in the
 dist/debian/ directory.
+
+Once the debian package is generated, you can install it using:
+
+    sudo apt install ./<package>.deb
+
+Note: The ./ is important - it tells apt to install from a local file
+rather than searching repositories.
+Replace the above path with the actual path to the generated debian file.
