For configuration answers the config.toml file.
baseURL = 'http://example.org/'
languageCode = 'en-us'
title = 'My New Hugo Site'
Hugo’s internal functions use the baseURL value to build absolute URLs. If you have a
domain name for your site you should change this value to reflect that domain.
The title value is where you’ll store the site’s title.
