 # Teslemetry Stream Library
-This is an asynchronous Python 3 library that connects to the Teslemetry Stream server and provides Tesla Fleet Telemetry using server side events.
+This is an asynchronous Python 3 library that connects to the Teslemetry Stream service and provides Tesla Fleet Telemetry using server sent events. The library allows you to listen to various telemetry signals from Tesla vehicles, and provides a convenient way to handle these signals using typed listen methods.
+
+## Capabilities
+- Connect to the Teslemetry Stream service
+- Listen to various telemetry signals from Tesla vehicles
+- Handle signals using typed listen methods
+- Write custom listeners for multiple signals
 
 ## Installation

 ## Example
 The following example puts the listening loop in the background, then stopping after 20 seconds.
 ```
+async def main():
+    async with aiohttp.ClientSession() as session:
+        async with TeslemetryStream(
+            access_token="<token>",
+            vin="<vin>", # for single vehicles
+            server="na.teslemetry.com" # or "eu.teslemetry.com"
+            session=session,
+        ) as stream:
+
+            def callback(event):
+                print(event["data"])
+
+            remove = stream.async_add_listener(callback)
+
+            print("Running")
+            await asyncio.sleep(60)
+            remove()
+```
+
+## Using Typed Listen Methods
+
+The library provides typed listen methods for various telemetry signals. These methods allow you to listen to specific signals and handle their data in a type-safe manner. Here is an example of using the typed listen methods:
+
+```python
+async def main():
+    async with aiohttp.ClientSession() as session:
+        async with TeslemetryStream(
+            access_token="<token>",
+            vin="<vin>", # for single vehicles
+            server="na.teslemetry.com" # or "eu.teslemetry.com"
+            session=session,
+        ) as stream:
+
+            vehicle = stream.get_vehicle("<vin>")
+
+            def battery_level_callback(battery_level):
+                print(f"Battery Level: {battery_level}")
+
+            def vehicle_speed_callback(vehicle_speed):
+                print(f"Vehicle Speed: {vehicle_speed}")
+
+            remove_battery_level_listener = vehicle.listen_BatteryLevel(battery_level_callback)
+            remove_vehicle_speed_listener = vehicle.listen_VehicleSpeed(vehicle_speed_callback)
+
+            print("Running")
+            await asyncio.sleep(60)
+            remove_battery_level_listener()
+            remove_vehicle_speed_listener()
+```

+## Writing Your Own Listener with Multiple Signals

+You can also write your own listener that listens to multiple signals. Here is an example of writing a custom listener:
