+Testing
+-------
+
+There are the tests that come from the examples in the Rust documentation
+and get transformed into KUnit tests. These can be run via KUnit. For example
+via ``kunit_tool`` (``kunit.py``) on the command line::
+
+	./tools/testing/kunit/kunit.py run --make_options LLVM=1 --arch x86_64 --kconfig_add CONFIG_RUST=y
+
+Alternatively, KUnit can run them as kernel built-in at boot. Refer to
+Documentation/dev-tools/kunit/index.rst for the general KUnit documentation
+and Documentation/dev-tools/kunit/architecture.rst for the details of kernel
+built-in vs. command line testing.
+
+Additionally, there are the ``#[test]`` tests. These can be run using
+the ``rusttest`` Make target::
+
+	make LLVM=1 rusttest
+
+This requires the kernel ``.config`` and downloads external repositories.
+It runs the ``#[test]`` tests on the host (currently) and thus is fairly
+limited in what these tests can test.
