I assume I must be missing something really obvious, but I cannot find any notes / documentation on how to edit config.yml.
After installation I get this message 
If you need to make additional configuration changes, you can modify the settings in ./bwdata/config.yml
However the file is blank and I cannot find any notes on what options are available.
I need to use my own certificate and DNS servers in the nginx config and assume this is the way to do that.
Never used docker before as I prefer real apps on the OS, so any help would be appreciated,
