-This folder contains tests for `vvi` that are called from `vv_test.py`.
+# Overview #
+
+This folder contains tests for the VVhitespace interpreter (`vvi`).
+
+# Instructions #
+
+Edit the shebang in `vv_test.py` to match your environment. For example:
+
+    FreeBSD 12: #!/usr/local/bin/python3.6
+    Debian 9  : #!/usr/bin/python3
+
+Build `vvc` and `vvi` in the source tree, if you haven't already.
+
+    vvs-repo/tests % cd .. && make clean all && cd tests
+
+Alternatively, edit the configuration block in `vv_test.py` to provide
+appropriate paths relative to this `tests` folder. 
+
+    compiler_path = '../vvc'
+    interpreter_path = '../vvi'
+
+With configuration now complete, execute the tests via `make test`.  A dot will
+appear for every successfully completed test. For example:
+
+    vvs-repo/tests % make test
+    Testing vvi:
+    .......................
+    vvs-repo/tests %
+
+If a test should fail, the name of the test will be printed in place of its
+dot.  For example, with an induced failure in the division command:
+
+    vvs-repo/tests % make test
+    Testing vvi:
+    ........
+    2004_arithmetic_division
+        Expected: A
+        Received: A113
+    ..............
+    vvs-repo/tests %
+
+If testing is aborted prematurely, say by a Ctrl-C initiated SIGINT, use `make
+clean` to remove any temporary files.
