-full TypeScript support.
+React Query Firebase provides a set of easy to use hooks for handling asynchronous tasks with Firebase in your React application.
+## Why should I use React Query Firebase?
+
+- **Backed by [React Query](https://react-query.tanstack.com)** - Unlike other solutions, hooks are built on top of [React Query](https://react-query.tanstack.com) which takes care of complex challenges
+such as caching, automatic refetching, realtime data subscriptions, pagination & infinite queries, mutations, SSR Support, data selectors, side effect handlers and more. You also get [DevTool](https://react-query.tanstack.com/devtools)
+support out of the box!
+- **Un-opinionated** - You provide the Query Keys, Configuration & Firebase instances which allows you full control over how the data is integrated and cached. You can also roll it alongside any existing Firebase usage.
+- **Performant & Efficient** - Whether your queries are one-off or realtime, the library is designed to be performant and efficient. Data fetching is handled via [Queries](https://react-query.tanstack.com/guides/queries) and 
+[Query Keys](https://react-query.tanstack.com/guides/query-keys), meaning components can share data and queries throughout your application.
+- **Mutations** - Sign a user in, delete a document, run a transaction, log an event... Don't worry about managing your own local state, React Query Firebase takes care of that for you via [Mutations](https://react-query.tanstack.com/guides/mutations).
+- **Fully Typed** - The library is built with and has full compatibility with TypeScript.
 
 > **Note**: The library supports the Firebase JS SDK v9 - [learn more about it here](https://firebase.googleblog.com/2021/08/the-new-firebase-js-sdk-now-ga.html)!

+## Example
 
-As an example, let's use a Firestore hook to fetch a document & run a transaction whilst easily handling loading and error state:
