How to care for a cat!?

Ok, so my mom found a kitty and it's my first kitten. I have no clue how to care for a cat. It's a female and has adapted pretty well to our home. We found her to days ago and is doing good but all I need to know is how to care for her. She's about 2-3 mounths old. I need all the info I can get. Thanks!!! :)
