check exercise slides of HMD

[fedoralina]

Check if there is any information on what we may need to include, as I remember some slides about

• how to include mixed initiative into dialog
• a certain action required for pizza ordering

Notes:

• [ ] add ToDo's for the first happy paths to the code
• [ ] make comments here on what we need to include
