Writing down some possible additions to the docker setup we have came across with @janickoR

• Adding disclaimer about Docker Desktop

  Disclaimer: Docker Desktop is not free for companies with more than 250 employees. Since we anticipate that most of the project developers will be Municipality of Bratislava employees, who currently don't have a license to use Docker Desktop, we advise using either Podman or Docker CLI, both of which are free alternatives.

• Adding example on how to start specific containers within Docker, so we can run the main application locally.

  
  docker run -p 5432:5432 --name postgres-local -e POSTGRES_USER=postgres -e POSTGRES_PASSWORD=postgres -e POSTGRES_DB=postgres -d postgres:latest

docker run -p 5672:5672 -p 15672:15672 --name rabbitmq-local -d heidiks/rabbitmq-delayed-message-exchange:3.12.10-management

(optional) add `--restart always` to start the containers automatically on docker start
