 The OpenPOWER ISA Technical Workgroup is the workgroup that governs over the POWER ISA specifications.
+
+
+The POWER ISA TWG will solicit proposals, Requests for Change (RFCs), review them, and publish approved additions to the POWER ISA specification.  
+Groups of proposals will be collected and published as a versioned specification on schedules determined by the WG.
+
+The ISA WG will :
+- solicit RFCs from both OpenPOWER Foundation members and non-members
+- create a process by which RFCs are submitted, evaluated, and approved.
+- The process will include the following concepts:
+  - The ISA WG will determine whether Contributions are Compatible.
+  - IBM will provide feedback on the availability of Architectural Resources and may assign provisional Architectural Resources if available.
+    If a Contribution is ultimately approved, IBM will commit specific Architectural Resources to the Contribution if appropriate resources
+    are available.
+  - The ISA WG will ensure that public RFCs are submitted with a Contribution/Feedback License per the IPR Policy.
+    provide public feedback on all public RFCs
+- Provide a maintainer for the POWER ISA specification source for the purpose of ensuring that updates to the document source are consistent with
+  approved Contributions.
