Documentation for setup

[makyo]

It would be lovely to have a README with some simple setup instructions for Docker environments.

I have only worked with Docker a few times have not worked with Dotnet web apps at all, and am doing my level best to get the database working with the postgres container with little luck:

mapserver-map_database-1   | 
mapserver-map_database-1   | PostgreSQL Database directory appears to contain a database; Skipping initialization

which is pretty clearly a config goof on my part, but I am unsure of how to get that into the app properly, even by attempting to fudge a connection string in the appropriate appsettings.*.yaml file.

Yea I definitely need to write some documentation for hosting this. 👍
