How to use this plug-in?

Hi! I hoping to find a plug-in that is setting the last part of the url based on the browser language. Is this one?

So my site is e.g. mywebsite.nl The plug-in changes the last part when the visitors browser language is in english: mywebsite.nl/en

If not. What does your plug-in do? (sorry it is not clear to me)

Many thanks in advance!
