Feature request / docs addition - Replace localhost with web address

[Jonathan]

Hi , Please could you add a feature/explain how to replace the localhost site generator with the final hosting address on the generated maps.

i.e

http://localhost:5000/

replace with

http://finaldestination.etc/

That sounds useful. Anyone willing to submit a PR for this?
