Documentation on hosting

[davean]

Can you please document how this should be run? In particular it seems there is a hard coded port and no option documented to configure for the system its running on.

[kozross]

snap provides any application built with it a set of standard options, which can be viewed with --help. This includes port setting, using the -p argument.

I will document this and push.

Edit: Should be addressed by 0c57de3.
