Missing steps in the readme

[Morgan-6Freedom]

Hello.
I tried to install ampache with the docker-compose and I have several issues because the readme was not clear enough for me. (I imagine if could be not clear enough for other people too)

It miss the part that say you need to have the /data/ folder at the side of the docker-compose.yml. Maybe the readme should states something like this :

You have to download the docker-compose.yml file and the data folder then put them side by side. Alternatively you can pull the whole git.

It should look like this :

Beside you talk about

chown www-data:www-data ./data/config -R

but not every linux come with a www-data group. So I suggest to change to :

chown 33:33 ./data/config -R

Thank you if you agree to modify the readme with those information

Thank you! I can confirm that this was not obvious to me either - you saved me a significant amount of troubleshooting!

i'll be working on better guides for this, the current docker-compose is not really an easy start without reading the contents.

it might be better to make it a very blank start file without volumes or at least a prep script.
