+# upb Lua bindings
+
+These are some bare-bones upb bindings for Lua.
+
+These bindings exist primarily for experimentation and testing.
+They are incomplete and are not really intended for use in any application.
+This is by no means a complete or supported protobuf library, and in fact
+we don't even claim it to be functional.
