+## What to do if a test fails for you
+
+This test suite was originally designed for a pre-1.0 version of the KDL
+specification. If you encounter a failure, it's likely that the test suite
+will need to be updated, rather than your parser itself. This test suite is
+NOT AUTHORITATIVE. If this test suite disagrees with the KDL spec in any way,
+the most desirable resolution is to send a PR to this repository to fix the
+test itself. Likewise, if you think a test succeeded but should not have,
+please send a PR.
+
+If you think the disagreement is due to a genuine error or oversight in the
+KDL specification, please open an issue explaining the matter and the change
+will be considered for the next version of the KDL spec.
