+## Running tests locally
+
+While we run extensive automatic testing on [Travis CI][travis-pqc] and [Appveyor][appveyor-pqc], most tests can also be run locally.
+To do this, make sure the following is installed:
+
+* Python 3.5+
+* `nosetests` or `nose2` (either for Python 3)
+
+Run the Python-based tests by going into the `test` directory and running `nosetests -v` or `nose2 -B -v`, depending on what you installed.
+If you have the `rednose` plugin for `nosetests` installed, run `nosetests --rednose` to get colored output.
+
+You may also run `python <testmodule>` where `<testmodule>` is any of the files starting with `test_` in the `test/` folder.
