 Using a venv will allow to use pip to install dependencies without the danger
 that the installed modules will interfere with the system installed ones.
+On some systems (esp. those with Python 2 *and* 3 installed), you have to
+address Python 3 explicitly by using the commands `python3` / `pip3` instead

-    python3 -m venv ledtag
+    python -m venv ledtag
     source ledtag/bin/activate
     pip install pyhidapi pyusb pillow

+    # python led-badge-11x44.py -m 6 -s 8 "Hello" "World!"
 
 if the udev rules are installed, you should be able to access the badge without sudo / root privileges.

     source ledtag/bin/activate
