If you're interested to help with development, these are rough instructions on how to build and run everything locally.
The Pi Zero is a bit too slow for development, so I generally build things
on my desktop computer and git push
them to a git repo the Pi to test.
$ poetry install --no-dev
$ cd frontend
$ yarn install
$ yarn build
$ cd ..
$ poetry run mariner
Running backend tests:
$ poetry green
Running frontend tests:
$ yarn --cwd frontend test
