+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS

+
+## 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.
