# Flows

Every sequence diagram, linked to the section it explains.

Every flow is a numbered sequence diagram with the same steps written out underneath. Each one now sits in the section it explains; this page links to them. Sign-in is in the OpenAPI contract. The rest are designed and marked that way.
