Summary:Simply installing `sinopia` does not create a config file (or even a
directory when it should be placed). Running `sinopia` for the first time
generates a default config file so it?s easier for the user to
configure it properly.

The readme is basically empty but contributing has a ton of useful information. Github's interface show everything in readme inline when you open the folder, so might as well make this information more visible.
