+  # One way to build a projects that uses gRPC is to just include the

+  # This approach is very simple to use, but the are some potential
+  # disadvantages:
+  # * it includes gRPC's CMakeLists.txt directly into your build script
+  #   without and that can make gRPC's internal setting interfere with your
+  #   own build.
+  # * depending on what's installed on your system, the contents of submodules
+  #   in gRPC's third_party/* might need to be available (and there might be
+  #   additional prerequisites required to build them). Consider using
+  #   the gRPC_*_PROVIDER options to fine-tune the expected behavior.

+
+A new Flutter project.
+
+## Getting Started
+
+This project is a starting point for a Flutter application.
+
+A few resources to get you started if this is your first Flutter project:
+
+- [Lab: Write your first Flutter app](https://docs.flutter.dev/get-started/codelab)
+- [Cookbook: Useful Flutter samples](https://docs.flutter.dev/cookbook)
+
+For help getting started with Flutter development, view the
+[online documentation](https://docs.flutter.dev/), which offers tutorials,
+samples, guidance on mobile development, and a full API reference.

+# Launch Screen Assets
+
+You can customize the launch screen with your own desired assets by replacing the image files in this directory.
+
+You can also do it by opening your Flutter project's Xcode project with `open ios/Runner.xcworkspace`, selecting `Runner/Assets.xcassets` in the Project Navigator and dropping in the desired images.
