+You can try out the latest version of detective from pypi without installing anything. If you click on the 'launch binder' button above, detective will be started in a Docker container online using the [Binderhub](https://binderhub.readthedocs.io) service. Run the example notebook to explore detective, and use the `Upload` button to upload your own `home-assistant_v2.db` database file for analysis. Note that all data is deleted when the container closes down, so this service is just for trying out detective.

 ### Auth helpers
 When querying the database, you might end up with user IDs and refresh token IDs. We've included a helper to help load the auth from Home Assistant and help you process this data.
