  # Assumptions made about the self-hosted runner:
  #
  #  1. Has installed the GitHub Actions self-hosted runner service
  #  2. Has nrfjprog already installed
  #  3. Has an environment variable defined for the serial port: CI_NRF52840DK_PORT
  #  4. Has credentials defined in the file $HOME/credentials_nrf52840dk.yml
  #  5. Has an environment variabled defined for the JTAG serial number of the nRF52.
  #
  # It is the responsibility of the self-hosted runner admin to ensure
  # these pre-conditions are met.
  #
  # For item 1, GitHub provides instructions when you add a new self-hosted runner
  # in Settings -> Actions -> Runners.
  #
  # For item 2, you'll need to install jlink and nrf-command-line-tools:
  #   https://www.segger.com/downloads/jlink/
  #   https://www.nordicsemi.com/Products/Development-tools/nrf-command-line-tools/download
  #
  # For item 3, this environment variable can be added to $HOME/runner_env.sh:
  #   export CI_NRF52840DK_PORT=/dev/ttyACM0
  #
  # For item 4, the file needs to have contents like:
  #
  # settings:
  #   wifi/ssid: mywifissid
  #   wifi/psk: mywifipassword
  #   golioth/psk-id: device@project
  #   golioth/psk: supersecret
  #
  # The golioth credentials need to match a device on coap.golioth.dev
  #
  # For item 5, you can discover the serial number of the nRF52 using this command:
  #   nrfjprog --ids
  # Once you know the serial number, you can add this to $HOME/runner_env.sh:
  #   export CI_NRF52840DK_SNR=723769314
