There are some markdown lint errors:

README.md:76 MD036/no-emphasis-as-heading/no-emphasis-as-header Emphasis used instead of a heading [Context: "1. Configure the default secre..."]
README.md:84 MD036/no-emphasis-as-heading/no-emphasis-as-header Emphasis used instead of a heading [Context: "2. Run docker-compose"]

Is this correct, i need to use docker compose up -d?

[m-ildefons]

-d detaches the process from the shell (aka. daemonizes the process), so you'll be dropped back to your shell while the docker-compose process continues in the background. This allows you to log out of the machine without killing the process or run other continue using the shell with other commands. It's entirely optional.
You can use docker-compose down to stop the containers later on.

What i mean is docker-compose vs docker compose. On my Ubuntu installation i get

$ which docker-compose                         
docker-compose not found

Regarding the -d. I prefer to not mention it in the docs because running it in front helps to watch what is going on. User that want to run it in background can simply add the -d on their own.

We're planning on reworking the docker-compose file soon-ish. We appreciate the contribution, but at this time we'll wait for the incoming rework of this file. Thanks!
