I'll try my best to help you, but you didn't really give out much about what you intend to write, so I'll just go out on a limb and offer suggestions.

When you write a prologue, you can describe something that happens:

>In the Past (Flashback, usually with the protagonist or describing an event that lead up to the events in chapter 1 and onwards.)

>In the Present (Usually something that doesn't directly relate to what happens in your first chapter, namely doesn't include your protagonist and all, if you know what I mean... there are exceptions of course.)

>In the Future (Some obscure future event - without directly stating it's the future, of course, just hinting at it - which is usually the climax or one of the climaxes in your story, and you begin in the first chapter with the events leading up to it...)

I don't know what you intend to do, but I'm a fan of the third option.

Also, when writing a prologue, regardless of which of the aforementioned you pick, you will usually introduce

>An Important Character (In this case, it all depends on what kind of character you are introducing - if you go for villain, my suggestion is to give some small insight on his motives, reasoning, trail of thought... hints that the reader can use to guess his identity later on in your story... if you go for protagonist, you usually want to make him do something 'regular', not really... protagonistish and stuff, unless it's the future.)

>An Important Event (Begin with the people involved, describe their emotions, their actions, some obscure dialogue, then begin describing the location with small details that somehow relate to the event, then start narrating the occurence itself.)

>An Important Place (Not really a very common option, and I wouldn't really know how to go on about this - mostly, if you want to describe the place most of your story takes part in; could be a city, a country, or a castle etc, start by giving out seemingly random details, such as the weather, the season, random things to build up an atmosphere. If it's an important location, like a house hiding an item of significance, you usually want to begin with the exterior, then describe the place from a visitor point-of-view, giving in a few of the sentiments someone would feel while entering the place etc.)

Well... that's about all I can give right now. If you want further help, you've got to give me a few more details on what you intend to start with etc.
