+# Simple Test Set for Joy Programming Language
+
+Each test consists of a snippet of Joy code along with the expected
+output (stdout and stderr) for a (conforming) Joy implementation.  They
+are run with make.
+
+For the explanation of how this test system works see:
+https://chrismorgan.info/blog/make-and-git-diff-test-harness/
+
+Set the JOY environment variable to point to the joy interpreter to test,
+e.g.:
+
+    export JOY="python -m joy -q"
+
+-or-
+
+    setenv JOY "python -m joy -q"
+
+or whatever for your shell.  Then run make.
+
+The general command line is, e.g.:
+
+    gmake -j
+
+To make all the tests, e.g.:
+
+    gmake -j --always-make
+
+The the ``g-`` prefix indicates that this is GNU make (or compatible), and
+the ``-j`` switch tells make to use multiple jobs to take advantage of
+multi-core systems.
