+How to test your contribution
+------------------------------
+
+Although `nose` and `doctest` are both used in code testing, it is adviable that unit tests are put in tests. `doctest` is incorporated only to make sure the code examples in documentation remain valid across different development releases.
+
+On Linux/Unix systems, please launch your tests like this::
+
+    $ make test
+
+On Windows systems, please issue this command::
+
+    > test.bat
