 ## Overview
-An example showing how to query [Azure Digital Twins](https://docs.microsoft.com/en-us/azure/digital-twins/how-to-manage-twin#create-a-digital-twin) from within PowerBI.
+An example showing how to query [Azure Digital Twins](https://docs.microsoft.com/en-us/azure/digital-twins/how-to-manage-twin#create-a-digital-twin) from within PowerBI. You could use this to query the current state of your IoT devices, for example, to use the [Anomaly Detector](https://docs.microsoft.com/en-gb/azure/cognitive-services/anomaly-detector/) cognitive service to check the state of outliers.
 
 powerbi-adt is available under the [MIT Licence](./LICENCE).
 
-Implemented use cases:
-- List all twins
+## Setting up
+1. Create an Azure Digital Twin
+2. Give yourself access to the data plane - add some example data - the [Azure Digital Twins explorer](https://github.com/Azure-Samples/digital-twins-explorer/) example data is a good start.
+3. Create a virtual environment for your Python setup, e.g. `python3 -m venv .venv`
+4. Install the requirements `pip install -r requirements-dev.txt`
+5. Copy the path to your venv
+6. [Enable python scripting](https://docs.microsoft.com/en-us/power-bi/connect-data/desktop-python-scripts#enable-python-scripting) in PowerBI
+7. Log in to Azure on the CLI with `az login`
+8. Import the **powerbi-query.py** as a [PowerBI datasource](https://docs.microsoft.com/en-us/power-bi/connect-data/desktop-python-scripts#run-your-python-script-and-import-data)
 
+### Example
