-A sample app for Firebase DataConnect
+## Introduction
+
+This quickstart is a movie tracker app to demonstrate the use of Firebase Data Connect
+ with a Cloud SQL database.
+
+For more information about Firebase Data Connect visit [the docs](https://firebase.google.com/docs/data-connect/).
+
+## Getting Started
+
+Follow these steps to get up and running with Firebase Data Connect. For more detailed instructions,
+check out the [official documentation](https://firebase.google.com/docs/data-connect/quickstart).
+
+### 0. Prerequisites
+- Latest version of [Xcode](https://developer.apple.com/xcode/)
+- Latest version of [Visual Studio Code](https://code.visualstudio.com/)
+- The [Firebase Data Connect VS Code Extension](https://marketplace.visualstudio.com/items?itemName=GoogleCloudTools.firebase-dataconnect-vscode)
+
+### 1. Connect to your Firebase project
+
+1. If you haven't already, create a Firebase project.
+    * In the [Firebase console](https://console.firebase.google.com), click
+        **Add project**, then follow the on-screen instructions.
+
+2. Upgrade your project to the Blaze plan. This lets you create a Cloud SQL
+    for PostgreSQL instance.
+
+    > Note: Though you set up billing in your Blaze upgrade, you won't be
+    charged for usage of Firebase Data Connect or the
+    [default Cloud SQL for PostgreSQL configuration](https://firebase.google.com/docs/data-connect/#pricing) during the preview.
+
+3. Navigate to the [Data Connect section](https://console.firebase.google.com/u/0/project/_/dataconnect)
+    of the Firebase console, click on the "Get Started" button and follow the setup workflow:
+     - Select a location for your Cloud SQL for PostgreSQL database (this sample uses `us-central1`). If you choose a different location, you'll also need to change the `data-connect-ios-sdk/Examples/FriendlyFlix/dataconnect/dataconnect.yaml` file. 
+     - Select the option to create a new Cloud SQL instance and fill in the following fields:
+       - Service ID: `dataconnect`
+       - Cloud SQL Instance ID: `fdc-sql`
+       - Database name: `fdcdb`
+4. Allow some time for the Cloud SQL instance to be provisioned. After it's provisioned, the instance
+   can be managed in the [Cloud Console](https://console.cloud.google.com/sql).
+
+5. If you haven’t already, add an iOS app to your Firebase project, using `com.google.firebase.samples.FriendlyFlix` as the bundle ID.
+ Click **Download GoogleService-Info.plist** to obtain your Firebase config file.
+
+### 2. Cloning the repository
+
+1. Clone this repository to your local machine:
+   ```sh
+   git clone https://github.com/firebase/data-connect-ios-sdk.git
+   ```
+
+2. Move the `GoogleService-Info.plist` config file (downloaded in the previous step) into the root folder of the sample app in the 
+  `data-connect-ios-sdk/Examples/FriendlyFlix/app/FriendlyFlix/FriendlyFlix/GoogleService-Info.plist` directory.
+
+### 3. Open in Visual Studio Code (VS Code)
+
+1. Open the `data-connect-ios-sdk/Examples/FriendlyFlix` directory in VS Code.
+2. Click on the Firebase Data Connect icon on the VS Code sidebar to load the Extension.
+   a. Sign in with your Google Account if you haven't already.
+3. Click on "Connect a Firebase project" and choose the project where you have set up Data Connect.
+4. Click on "Start Emulators" - this should generate the Swift SDK for you and start the emulators.
+
+### 4. Populate the database
+In VS Code, open the `data-connect-ios-sdk/Examples/FriendlyFlix/dataconnect/data_seed.gql` file and click the
+ `Run (local)` button at the top of the file.
+
+If you’d like to confirm that the data was correctly inserted,
+open `data-connect-ios-sdk/Examples/FriendlyFlix/dataconnect/movie-connector/queries.gql` and run the `ListMovies` query.
+
+### 5. Running the app
+
+Press the Run button in Xcode to run the sample app on the iOS Simulator.
