Creatine for Women

Can someone explain to me the uses of creatine? I know it's commonly used to help build lean muscle, while in a caloric surplus.. but is that all their is too it? Does it cause one to gain more fat? Not sure if i should dabble into it, always hearing about it but dont feel like I know enough about it. What is the recommended dose/when does one take it? Is it taken in pill form or powder form?

Thanks !
