+Simple realtime streaming SDK for sondehub.org V2 API.
+
+```
+sondehub.Stream(sondes=["serial number"], on_message=callback)
+```
+If no `sondes` list is provided then all radiosondes will be streamed.
+
+On message callback will contain a python dictonary using the [Universal Sonde Telemetry Format](https://github.com/projecthorus/radiosonde_auto_rx/wiki/Suggested-Universal-Sonde-Telemetry-Format)
+
+Example Usage
+--
+
+```python
+import sondehub
+
+def on_message(message):
+    print(message)
+
+test = sondehub.Stream(sondes=["R3320848"], on_message=on_message)
+#test = sondehub.Stream(on_message=on_message)
+while 1:
+    pass
+
+```
+
+CLI Usage
+```sh
+# all radiosondes
+sondehub
+# single radiosonde
+sondehub --serial "IMET-73217972"
+# multiple radiosondes
+sondehub --serial "IMET-73217972" --serial "IMET-73217973"
