[jQuery] how to make a function with JQuery


Hello every one,
I'm a new user of JQuery and i'm trying to use it on a web site that
i'm building. Keep in mind that i'm also new on the web.
So i wanted to know:
- How to define a function with JQuery.
- Does it works similary like woring with Javascript and DOM ?
- Shall my function, if allowed, be defined in the $(document).ready
() ... ?
thank
