 Anuket Documentation
 ====================
 
-The Anuket project facilitates the development and evolution
-of cloud components across various open source ecosystems.
-Through preparation of reference specifications,
-system level integration, testing and deployment, Anuket creates
-reference implementations and conformance tests to accelerate the
-transformation of enterprise
-and service provider networks. Participation is open to anyone,
-whether you are an employee of a member company or just passionate
-about network transformation.
+The mission of the Anuket project is to empower the global communications community by creating and developing reference
+cloud infrastructure models, architectures, tools, and programs to deliver network services faster, more reliably, and
+securely.
+
+Anuket approaches its mission by providing a set of cloud infrastructure reference
+specifications, reference implementations, conformance tests, testing tools, testing frameworks and implementation
+projects.

+Documentation for Anuket Users
+------------------------------
+
+These documents are targeted to the users of the different Anuket sub-projects and here they are organized by
+sub-project categories.
 
 Anuket Specifications
-----------------------
+~~~~~~~~~~~~~~~~~~~~~
+
+:doc:`Anuket Specifications <cntt:index>` provide reference specifications for cloud infrastructures and their
+workloads. The specifications are organized to the following documents:
 
-:doc:`Anuket Specifications <cntt:index>`
+* Reference Model (RM) - a technology independent specification of cloud infrastructures for telecom workloads
+* Reference Architecture (RA1) for OpenStack based cloud infrastructure - a specification of an OpenStack cloud
+  infrastructure based on the requirements of the Reference Model 
+* Reference Conformance (RC1) for RA1 based Implementations - an automatic conformance testing framework to test RA1
+  conformance of OpenStack cloud infrastrucutres and their workloads
+* Reference Implementation based on RA1 specifications (RI1) - a blueprint to build an OpenStack cloud based on the
+  requirements of the RA1 specifications
+* Reference Architecture (RA2) for Kubernetes based cloud infrastructure - a specification of a Kubernetes container
+  orchestration platform based on the requirements of the Reference Model
+* Reference Conformance (RC2) for RA2 based Implementations - an automatic conformance testing framework to test RA2
+  conformance of OpenStack cloud infrastrucutres and their workloads
+* Reference Implementation based on RA2 specifications (RI2) - a blueprint to build a Kubernetes container orchestration
+  platform based on the RA2 specificcations.
