How to watch movies in infuse2 from trakt ?

I am new in infuse application app and I would like to know how to watch movies in infuse2 from trakt.

Just to clarify, Infuse is an app that allows for a wider range of content to be played on an iPhone or iPad, and also provides many flexible options for syncing or streaming content.

trakt is a service that syncs your watched history, and recommends other content you may like. It doesn't provide any video content in and of itself.
