-'Kohn' Use Cases and Requirements
-=================================
-
-
-The section includes use cases and functional requirements which have been
-officially verified in the release.
-
-For each use case or functional requirement, you can find contact names and a
-link to the associated documentation.
-
-This documentation deals with
-
-  1. What has been implemented
-  2. Step by step instructions to deploy and execute the tests, including the
-     links to download the related assets and resources
-  3. Known issues and workarounds

+Use Cases, Blueprints, Requirements
+===================================
+
+ONAP use cases are descriptions of how a user interacts with an ONAP system to
+achieve a specific goal. They describe the actions that the user takes, the
+system’s responses, and any conditions or tasks that must be met for the
+interaction to occur. ONAP use cases are used to identify and define the
+functional requirements of the ONAP system.
+
+ONAP requirements are statements that describe what the ONAP system must do,
+how it should behave , and what constraints it must operate under. 
+ONAP requirements are typically divided into functional requirements, which
+describe what the ONAP system must do, and non-functional requirements, which
+describe how the ONAP system should behave or perform.
+
+ONAP blueprint is a high-level design document that provides an overview of the
+ONAP system’s architecture and components. The blueprint typically includes
+diagrams that illustrate the ONAP system’s structure and relationships between
+components, as well as descriptions of each ONAP component’s function and
+interface.
