In your web documentation at http://docs.donkeycar.com/guide/build_hardware/, the link to the webpage entitled Roll Your Own is broken. The link is to http://docs.donkeycar.com/roll_your_own.md but it the link should instead lead to http://docs.donkeycar.com/roll_your_own/.

Hopefully this helps.

A requirements.txt would help others install the required packages.

In the readme.me you list cv2 for example, which isn't found on pypi by that name.
https://pypi.org/search/?q=cv2

Hey! Great work, that could be a great example in ML courses.
It would maybe benefit from having a pip requirement.txt files that would automatize the install:

Pillow==7.0.0
opencv-python==4.2.0.32
torch==1.4.0
numpy==1.18.2
matplotlib==3.0.3

and the installation would sum up to:

python3 -m pip install -r requirement.txt

Currently pressing ctrl+c simply exits the program.
It would be nice if we can handle that and print something nice like Canceled by the user or something similar.
