@Janet , Luke Cyca and I used it a while back and updated the Wiki with instructions that will be enough to get you going.
I would recommend picking some of the stuff off the shelf and playing around with it. When you get your final material you should do some test cuts to get the right speed and pressure for that material.
Also a new blade would probably make life easier if the EPC would cover it.
Also you’ll want transfer paper, a scalpel, and a squeegy to get rid of bubbles.
If that’s not enough I can run you through the basics some day, it’ll only take about 20 minutes as I’m not a master vinyler myself. Although I haven’t made it to the hackspace in ages, bloody office jobs! :
