Generating and Using IMDF

My team and I have signed up for the apple indoor program and we're keen to develop an AR indoor navigation proof of concept app for our officepark. I've emailed Apple dev support and imdfquestions@apple.com on generating IMDF files from floor plans to no avail. Does anyone know the steps to this process? I've checked https://register.apple.com/resources/indoor/Apple-Indoor-Maps-Guidelines.pdf and https://register.apple.com/resources/imdf/ as well. Thanks!
