Outdoor Revolution Easi porch

Can anyone help, we bought the above two years ago, it seemed a good idea at the time and we have never used it, we erected today on the drive (did not peg it out for obvious reasons)  Can anyone advise me what the three straps with buckles are for.I have
never seen this on any awning that we have had over the years, are you supposed  to lay a ground sheet on top of these straps or what, We intend taking it to Dorset in two weeks time as at present I am in no fit state to erect our full awning. Thanks
