+# Overview
+
+OpenCog Hyperon is a substantially revised, novel version of OpenCog - which is currently at an active
+pre-alpha stage of development and experimentation. One of the focuses in the Hyperon design is a successor
+to the OpenCog Classic Atomese language with clear semantics supporting meta-language features,
+different types of inference, etc. What we have landed on is an "Atomese 2" language called MeTTa (Meta Type Talk).
+
+One can run MeTTa script from command line:
