That's to say: They all have add(), addAll(), contains(), etc. methods.

I'm playing around with RISC-V and qemu this week and found a great example of an easy type of PR you can do!

If the docs are open source, feel free to take that opportunity to make a PR and get some real world practice with git(hub).

Joystick plugs into beagleboard-xm rev C and uses the "controlArmWithJoystick.py" file in the github repo listed below. The beagleboard takes the joystick input and sends it over serial connection to the arduino which processes the input with the file "sketchbook/robot.ino" found in the repo below. Then the arduino sends signals to a PWM board that controls four servos.
