Garmin ANT+ dongle setup

I’m getting my setup sorted for Zwift at the moment and want to make sure everything is sorted for when my new computer arrives so I can start riding straight away

I’ve ordered the Garmin ANT+ USB dongle - http://www.amazon.co.uk/gp/product/B00CM381SQ?psc=1&redirect=true&ref_=oh_aui_detailpage_o00_s00

Do I literally just plug it into my PC and then launch Zwift and off I go? Or do I need to download some software to get the dongle working in the first place?

I’ve used Zwift on Windows 8.1 and now 10 and yes, just plugged it in and off I go.
