[Benjamin W. Broersma]

The current requirement:

Internet.nl/documentation/Docker-getting-started.md

Lines 9 to 11 in 49d58dd

 - [Docker](https://docs.docker.com/get-docker/) for Linux, (supported, tested version 24.0.2) 
 - [Docker](https://docs.docker.com/get-docker/) for Mac (supported, tested version 4.21.0) 
 - [Colima](https://github.com/abiosoft/colima) for Mac (recommended, tested version 0.5.5) 

Is no longer valid since this nice PR:

• #1324

It will result in the error:

$ make up env=develop
docker compose  --env-file=docker/defaults.env --env-file=docker/develop.env --env-file=docker/local.env up --wait --no-build --remove-orphans

See the Configs top-level elements documentation:

ℹ️ Note

environment and content attributes are available with Docker Compose version 2.23.1 and later.

This compose version is packaged in docker engine 25.0.0.

Docker desktop should be at least 4.26.0 which includes Compose v2.23.3.
