+## Digital Twin Tutorial
+
+These notebooks will show you how to create a graph and interact with it through the Python API. It will build a venue and allow you to measure the customer satisfaction of people as the pass through the system. 
+
+
+You will need: 
+* A conda environment with the latest `Azure-Digital-Twin SDK`
+* The Azure CLI tools for authentication
+* The digital twin explorer
+* A digital twin account, where you have sufficient permission. 
+
+
+The perspective of these notebooks is from the role of the **Analyst** not an application. The purpose is to use the graph to get insights on customers. This would allow you to query the API in real time, as events are happening. 
+
