+## Quick Start
+
+The `frequenz-dispatch` library provides a high-level interface to interact
+with the dispatch API. Here's a minimal example to get you started:
+
+```python
+import os
+from datetime import timedelta
+from frequenz.dispatch import Dispatcher
+
+async def main():
+    # Configure connection to dispatch API
+    url = os.getenv("DISPATCH_API_URL", "grpc://your-dispatch-url.com")
+    key = os.getenv("DISPATCH_API_KEY", "your-api-key")
+    microgrid_id = 1
+    
+    # Create and use the dispatcher
+    async with Dispatcher(
+        microgrid_id=microgrid_id,
+        server_url=url,
+        key=key,
+    ) as dispatcher:
+        # Your dispatch logic here
+        print("Dispatcher ready!")
+```
+
+For complete examples and advanced usage, see the [Usage](#usage) section below.
 
 ## Usage
 
-The [`Dispatcher` class](https://frequenz-floss.github.io/frequenz-dispatch-python/v0.1/reference/frequenz/dispatch/#frequenz.dispatch.Dispatcher), the main entry point for the API, provides two channels:
