how do i Intergrate Mircosites into Apps?

Please can someone help me out here..

I need to host a site i have designed on dreamweaver, using any facebook app... my only problem is that i can find the app(i have searched plenty of them)... or maybe its my coding thats wrong, im still in the learing process of html and css.. but i still know my way around dreamweaver.. when i use facebook and intergrate a mircosite into it.. do i need my index.html , contact.html, agenda.html to be fitted into one page eg fullfacebooksite.html ?
and if not, how do i upload the content??
I have a place to host my images.. just dont know what to do from here...

Please can someone explain the process to me...

Thank you
