+Automated testing
+=================
+
+centaur comes with a suite of automated tests. Run
+    make check
+in the top-level directory to build elfucli and run the tests.
+
+Temporary files will be created in tests/build/ and cleaned
+up on 'make clean'.
+
+See the test scripts themselves for more specific documentation.
