# Build Your First React Native app

> **NOTE** The Getting Started docs show you how to build your first Mitter.io app with our cloud-hosted sandbox only.
>
> To use it with your docker container, simply change the base API Url (when creating the mitter object) to the address of your running docker container.

To build your first react native app, you can start by using the react native starter app for mitter.io. To get it, clone the repo:

```
git clone https://github.com/mitterio/react-native-starter.git
```

And then use `yarn` or `npm` to install all the dependencies:

```
yarn install # or npm install
```

Unlike the other starter apps, the react-native apps require some additional setup from your side before the application can be run. To do so, follow the setup instructions on the [React native reference](https://docs.mitter.io/sdks/web/for-react-native) page.

Once your application is setup, you can follow the [tutorial for your first web app](https://docs.mitter.io/getting-started/build-your-first-react-native-app) as it uses the exact same components/modules and API for the starter app.
