The Issue

• Support Pimcore CMS #5843 requests Pimcore support

We'll want more input from the Pimcore community, but this adds a basic quickstart.

@80982proton would love to have your review here.

Looks good so far, there are still some fine details which you will have to install yourself! There is also the "symfony consumer command" that you have to start! https://github.com/pimcore/skeleton/blob/11.x/.docker/supervisord.conf

@SuperFlySly could you please be explicit about

there are still some fine details which you will have to install yourself

Were you just referring to the "Recommended but not required" things in your screenshot? Should we be telling them how to do everything?

We can add the symfony consumer command with web_extra_daemons I guess (that installs in supervisord)

@SuperFlySly I've added the consumer as web_extra_daemon, would love your review again.

It looks to me like the other "recommended" things aren't something that would need to be done in a "quickstart", true?

I'm going to go with this, and we'll learn from the Pimcore community as they arrive! Thanks for the help everybody.
