+# Protobuf Unit Tests
+
+This directory contains wrappers around the Python unit tests defined in
+the protobuf repo.  Python+upb is intended to be a drop-in replacement for
+protobuf Python, so we should be able to pass the same set of unit tests.
+
+Our wrappers contain exclusion lists for tests we know we are not currently
+passing.  Ideally these exclusion lists will become empty once Python+upb is
+fully implemented.  However there may be a few edge cases that we decide
+are not worth matching with perfect parity.
