hello, I’m trying to do a testrun on my local environment to see if I can get my forum migrated to discourse.
I used this install guide to install discourse
I have a phpbb3 database export locally.
I have installed a local discourse on my mac with docker for desktop.
I am now trying to follow the instructions in this topic but I get stuck because I use docker, but not ubuntu, and it is local environment. So I don’t know how to proceed 
there is no app.yml in my discourse directory.
could anyone help me with what steps to take ?
many thanks in advance!
