 ## Implementation
 This section is for Lionel's awesome pictures and descriptions of the flow in our use case
 
+### Code for [Web Sequence Diagram](https://www.websequencediagrams.com/):
+Copy and paste the code below into the [Web Sequence Diagram](https://www.websequencediagrams.com/) webpage to generate the flow diagram

 ## Method
 This section will show an implementation of verifiable claims that allows for selective disclosure of claim attributes. In order facilitate understanding of the implementation, we first provide a section providing a view of topics in number theory and cryptography.
