+# A voice to voice app for React Native (Expo)
+
+This demo is meant to showcase a basic voice to voice app that uses [Daily's bots](https://bots.daily.co).
+
+## Prerequisites
+
+- [Sign up for a Daily bots account](https://bots.daily.co/sign-up).
+
+## Usage
+
+### Expo requirements
+
+This project cannot be used with an [Expo Go](https://docs.expo.dev/workflow/expo-go/) app because [it requires custom native code](https://docs.expo.io/workflow/customizing/).
+
+When a project requires custom native code or a config plugin, we need to transition from using [Expo Go](https://docs.expo.dev/workflow/expo-go/)
+to a [development build](https://docs.expo.dev/development/introduction/).
+
+More details about the custom native code used by this demo can be found in [rn-daily-js-expo-config-plugin](https://github.com/daily-co/rn-daily-js-expo-config-plugin).
+
+### Building remotely
+
+If you do not have experience with Xcode and Android Studio builds or do not have them installed locally on your computer, you will need to follow [this guide from Expo to use EAS Build](https://docs.expo.dev/development/create-development-builds/#create-and-install-eas-build).
+
+### Building locally
+
+You will need to have installed locally on your computer:
+- [Xcode](https://developer.apple.com/xcode/) to build for iOS;
+- [Android Studio](https://developer.android.com/studio) to build for Android;
+
+#### Install the demo dependencies
+
+```bash
+# Use the version of node specified in .nvmrc
+nvm i
+
+# Install dependencies
+npm i
+
+# Before a native app can be compiled, the native source code must be generated.
+npx expo prebuild
+```
+
+#### Running on Android
+
+After plugging in an Android device [configured for debugging](https://developer.android.com/studio/debug/dev-options), run the following command:
+
+```
+npm run android
+```
+
+#### Running on iOS
+
+First, you'll need to do a one-time setup. This is required to build to a physical device.
+
+If you're familiar with Xcode, open `ios/RNDailybots.xcworkspace` and, in the target settings, provide a development team registered with Apple.
+
+If you're newer to Xcode, here are some more detailed instructions to get you started.
+
+First, open the project in Xcode. Make sure to specifically select `RNDailybots.xcworkspace` from `/ios`. The `/ios` directory will have been generated by running `npx expo prebuild` as instructed above. This is also a good time to plug in your iOS device to be sure the following steps are successful.
+
+From the main menu, select `Settings` and then `Accounts`. Click the `+` sign to add an account (e.g. an Apple ID).
+

+
+Once an account is added, perform the following steps:
+
+ 1. Close `Settings`.
+ 1. Select the folder icon in the top left corner.
+ 1. Select `RNDailybots` from the side panel
+ 1. Navigate to `Signing & Capabilities` in the top nav bar.
+ 1. Open the "Team" dropdown
+ 1. Select the account added in the previous step.
+
+The "Signing Certificate" section should update accordingly with your account information.

+
+**Troubleshooting common errors:**
+
+- If you see the error `Change your bundle identifier to a unique string to try again`, update the "Bundle Identifier" input in `Signing & Capabilities` to make it unique. This should resolve the error.
+
+- If you see an error that says `Xcode was unable to launch because it has an invalid code signature, inadequate entitlements or its profile has not been explicitly trusted by the user`, you may need to update the settings on your iPhone to enable the required permissions as follows:
+
+1. Open `Settings` on your iPhone
+1. Select `General`, then `Device Management`
+1. Click `Trust` for DailyPlayground
+
+- You may also be prompted to enter you login keychain password. Be sure to click `Always trust` to avoid the prompt showing multiple times.
+
+After, run the following command:
+```
+npm run ios
+```
