Installed the odin-api skill to ${DEST}

Two things left, both one-time:

  1. Create a token: Odin dashboard -> Profile -> Personal Access Tokens
  2. Export it, along with the API address for your environment:

       export ODIN_API_TOKEN="opat_..."
       export ODIN_API_BASE_URL="https://api.odinhelp.com"

Then check it works:

       "${DEST}/scripts/odin" preflight
