             added or modified. Instead, enable all tests
             which have satisfied dependencies by adding
             ``CONFIG_KUNIT_ALL_TESTS=y`` to your ``.kunitconfig``.
+- ``--kunitconfig``: Specifies the path to the ``.kunitconfig`` file.
+  This Kconfig fragment enables KUnit tests. The "/.kunitconfig" gets
+  appended to the path specified. For example, If a directory path "lib/kunit"
+  is given, the complete path will be "lib/kunit/.kunitconfig".
+- ``--kconfig_add``: Specifies additional configuration options to be
+  appended to the ``.kunitconfig`` file. For example, ``CONFIG_KASAN=y``.
+- ``--arch``: Runs tests with the specified architecture. The architecture
+  specified must match the string passed to the ARCH make parameter.
+  For example, i386, x86_64, arm, um, etc. Non-UML architectures run on QEMU.
+  Default to 'um'.
+- ``--cross_compile``: Specifies the Kbuild toolchain. It passes the
+  same argument as passed to the ``CROSS_COMPILE`` variable used by
+  Kbuild. This will be the prefix for the toolchain
+  binaries such as GCC. For example:
+  - ``sparc64-linux-gnu`` if we have the sparc toolchain installed on
+    our system.
+  - ``$HOME/toolchains/microblaze/gcc-9.2.0-nolibc/microblaze-linux/bin/microblaze-linux``
+    if we have downloaded the microblaze toolchain from the 0-day
+    website to a specified path in our home directory called toolchains.
+- ``--qemu_config``: Specifies the path to the file containing a
+  custom qemu architecture definition. This should be a python file
+  containing a QemuArchParams object.
+- ``--qemu_args``: Specifies additional QEMU arguments, for example, "-smp 8".
+- ``--jobs``: Specifies the number of jobs (commands) to run simultaneously.
+  By default, this is set to the number of cores on your system.
+- ``--timeout``: Specifies the maximum number of seconds allowed for all tests to run.
+  This does not include the time taken to build the tests.
+- ``--kernel_args``: Specifies the kernel command-line arguments. Might be repeated.
+- ``--run_isolated``: If set, boots the kernel for each individual suite/test.
+  This is useful for debugging a non-hermetic test, one that
+  might pass/fail based on what ran before it.
+- ``--raw_output``: If set, generates unformatted output from kernel.
+  If set to ``--raw_output=kunit``, filters to just KUnit output.
+- ``--json``: If set, it stores the test results in a JSON format and prints to stdout or
+  saves to a file if a filename is specified.
