Hi there from sunny Bali (although at the moment in deepest darkest Java)
Personally just stick with Foundation Framer right now, because it is a great app for creating great web-sites that are responsive. The problem is that it doesn't yet have much in the way of information that is easy for a newcomer to get anything workable from.
Foundation Framer works from Mobile size viewport up to large screens, which also for anyone new to this concept is a very daunting thing, but one you get the hang of it you will wonder how you ever managed before.
My best advice for the moment would be to forget about trying to produce something that is going to be anything like a finished project, just play with it and take it step by step.
Get a simple one page design down on paper (or however you thought about it and planned it out before) there are some useful tips and suggestions within the knowledge/ articles for RSD (which will help you understand the system about rows, columns subgrids etc etc (all be it opposite way to do things ié RSD starts from desktop and works down to mobile sizes) it is basically the same principle. There are some video's made bt other users available on You yube (sorry I can't provide links or anything as here in Indonesia we get blocked by you-tube for some things, and for some obscure reason those videos get blocked for me.
I also have helped a couple of people out with FF and RSD by interacting via e-mail and I make my own video made especially for the situation for others to follow, if you would like for me to help you get going you could contact me by e-mail (on my profile) and I would be happy to help guide you through the basics.
Stick at it don't get dispondent, once you get going it is really a fantastic tool to add to your weaponary for producing great web-sites.
Take care and have a great day everybody wherever in the world you are.
