 ===========
 
 .. note::
-    We are recently migrating BMV2 version of ``fabric.p4`` to ``fabric-tna`` repository.
-    We will be able to build a software emulated environment for SD-Fabric once that is done.
+    We have recently migrated the BMV2 version of ``fabric.p4`` to ``fabric-tna`` repository (and renamed it to ``fabric-v1model.p4``).
+    We plan to build a software-emulated, Docker-based environment using ``fabric-v1model.p4``
+    such that people can easily try out SD-Fabric without hardware equipments.
+    We also plan to use the same environment for SD-Fabric smoke test in the future.
     Stay tuned.
