+The demos were made based on the [web UI](https://microsoft.github.io/TaskWeaver/docs/usage/webui), which is better for displaying the generated artifacts such as images. 
+The demos could also be conducted in the command line interface. 
 
 #### Example 1: Pull data from a database and apply an anomaly detection algorithm
 In this example, we will show you how to use TaskWeaver to pull data from a database and apply an anomaly detection algorithm.
