 The application requires a Postgres database instance to be made available to the backend. Setting up a local database
 is handled by the backend start command.

 See the README files of each of those environments ([backend](./backend/README.md), [frontend](./frontend/README.md)) for specific requirements around `*.env` files that aren't committed with the code.
