I sugget to remove last sentence - we 3.2 now, and say smth like "Fuel 3.2 provides both UI for easy to use operations and CLI for providing even more configurability. Both UI and CLI use the same REST API service of Fuel, which can be used to drive Fuel from your applications." - and to have a link to REST API here: http://docs.mirantis.com/fuel-dev/develop/api_doc.html
