Modifying the readme
add support for explicit subdomains

this way, if you link something as foo.example, it will be reachable
from foo.example.dev, or more generally $prefix.foo.example.dev.

This is needed at my work since we have several apps that need to run on
the same domain, so it's easier to set up all the apps as
app-name.company-domain.dev.

This should be a backwards-compatible change, since arbitrary subdomains
still work in the case that was supported before.
