-# OR using Yarn
-yarn start
 ```
 
-## Step 2: Build and run your app
+## Theme
-
+- Primary: #5B7CE6
-With Metro running, open a new terminal window/pane from the root of your React Native project, and use one of the following commands to build and run your Android or iOS app:
+- Secondary: #7B94F0
-
+- Tertiary: #E8EFFF
-### Android
+- Quaternary: #3B5998
+- ... (see `shared/src/theme/colors.ts`)
 
+## Setup
+1. Install dependencies:
    ```sh
-# Using npm
+   npm install
-npm run android
+   ```
-
+2. Run the app:
-# OR using Yarn
+   ```sh
-yarn android
+   npm run android # or npm run ios
    ```
 
-### iOS

-The first time you create a new project, run the Ruby bundler to install CocoaPods itself:
-
-```sh
-bundle install
-```
-
-Then, and every time you update your native dependencies, run:
-
-```sh
-bundle exec pod install
-```
-
-For more information, please visit [CocoaPods Getting Started guide](https://guides.cocoapods.org/using/getting-started.html).
-
-```sh
-# Using npm
-npm run ios
-
-# OR using Yarn
-yarn ios
-```
-
-If everything is set up correctly, you should see your new app running in the Android Emulator, iOS Simulator, or your connected device.
-
-This is one way to run your app — you can also build it directly from Android Studio or Xcode.
