I'm going to play in my first casino tourney...first time playing live

[celiboy]

A local casino has a $10 MTT once a week and I am going to be playing in it. I have read posts on playing live so I think I will be fine on that end of it and I think this is a better introduction for me than playing at a 3/6 table as the most I can loose is 10 bucks. The question i have is regarding re-buys.

This tournament has $5 re-buys. I don't understand what this means. I think it means that you can re-buy a certain amount of chips up to a pre determined blind level if your stack size is below a certain amount before that point. Is this correct? Generally can you only re-buy once? If you do re-buy do you do so from the dealer? Any help would be appreciated.
