+The unittest Python module adds some simple infrastructure that allows to
+unittest Python functions defined in BitBake files.
 
 ## Running the tests
 
-You can run the tests using avocado with `avocado --show=app,test run testsuite/unittests/`
-or by using the buildin module with `python3 -m unittest discover testsuite/unittests/`
+Run all Python unit tests with:
+
+```sh
+scripts/run-tests.sh -t unittest
+```
+
+Or by using the built-in module: `python3 -m unittest discover testsuite/unittests/`.
+
+Run a specific test by its unittest name:
+
+```sh
+scripts/run-tests.sh -t unittest -p test=test_image_account_extension.TestImageAccountExtensionImageCreateUsers.test_new_user
+```
 
 ## Creating new tests
 
 See the [unittest documentation](https://docs.python.org/3/library/unittest.html)
 on how to create a test module and name it test_*bitbake_module_name*.py
 
-Use the function `load_function(file_name: str, function_name: str) -> Callable`
-in the bitbake module to load the function.
+Use `load_function(file_name, function_name)` from `bitbake.py` to load regular
+Python functions from BitBake files.
 
 Example:
 ```python
