No examples in docs using hooks

### Are you submitting a **bug report** or a **feature request**?

### What is the current behavior?

No examples using the useForm or useField hooks. That show how to properly use them while keeping performance in mind.

### What is the expected behavior?

Some examples. Is it ok to do:

```
const MyForm = () => {
useForm()
useField()
useField()
useField()

}
```

Won't this rerender the whole form anytime any field updates?
