Zurb Foundation and _s (underscores)

Hello all,

I am currently developing a custom theme using foundation and _s I had a few questions.
I have followed this tutorial Here enqued all my script etc and now its working. My only concern is the jquery, on some forums is says that i have to deregister the jquery and then register another one etc. On some forums its says that i have to use a non conflict mode while others tell me just to enque it and thats it. Another thing is the nav menu, which is extremely confusing. Here you can find the sample theme used in the tutorial. If anyone knows of these concern and the proper way to execute them i would really appreciate the help. I would like this site to be “future” proof so it wont break on updates etc.
