+Template for creating Google Cloud Run applications in Dart. Based on documentation from https://github.com/GoogleCloudPlatform/functions-framework-dart.
+
+The functions framework is nice for very simple applications, but isn't great if you want more control over your server behavior.
+
+## Prerequisites
+- Have a general idea how to set up Cloud Run. This is not comprehensive documentation.
+
+## Usage
+1. Create a new project based on this template
+2. Compose your server in `bin/server.dart`
+3. Edit `deploy.sh` to use the desired parameters
+4. Run `deploy.sh` to deploy your application
