Now we arrive at the strumming part. Try to practise slowly so you come familiar with the rythm. After that you can build up speed. Check first the video with the slow rythm so that you understand how it is played. You stay in the same chord as the opening riff. The ringfinger is alternating with the middle finger.The edge uses a lot of muting of the strings during the song. Try to improvise the way you like it.
