[dancer-users] D2: Where should I place the config.yml file?

It's not clear at all from Dancer2's documentation: "Dancer2 will first look for the file /config.ext / (where .ext is the type of configuration file you are using) in the root directory of your application." What is "the root directory of my application"? All I know is that I created a simple app.psgi in some directory and running it with plackup. I placed config.yml right next to it, but it's not getting read. Can we please fix the documentation a bit so it makes more sense? Thanks,
