 ## Connect Form {#ConnectForm}
 
-When we are building forms, there are times when our input lives inside of deeply nested component trees, and that's when [FormContext](/docs/useFormContext) comes in handy. However, we can further improve the Developer Experience by creating a `ConnectForm` component and leveraging React's [renderProps](https://reactjs.org/docs/render-props.html). The benefit is you can connect your input with React Hook Form much easier.

 ## FormProvider Performance {#FormProviderPerformance}
 
-React Hook Form's [FormProvider](/docs#useFormContext) is built upon [React's Context](https://reactjs.org/docs/context.html) API. It solves the problem where data is passed through the component tree without having to pass props down manually at every level. This also causes the component tree to trigger a re-render when React Hook Form triggers a state update, but we can still optimise our App if required via the example below.
