+ament_lint_auto_py
+==================
+
+The package simplifies using multiple linters as part of pytest tests.
+
+To have `ament_lint_auto_py` collect and run the linters include it in the `package.xml`
+
+``package.xml``:
+
+.. code:: xml
+
+    <test_depend>ament_lint_auto_py</test_depend>
+
+
+The set of linters to be used is then only specified in the package manifest as
+test dependencies.
+
+``package.xml``:
+
+.. code:: xml
+
+    <test_depend>ament_lint_auto_py</test_depend>
+
+    <!-- add test dependencies on any linter, e.g. -->
+    <test_depend>ament_clang_format</test_depend>
+    <test_depend>ament_cppcheck</test_depend>
+    <test_depend>ament_pycodestyle</test_depend>
+
+Since recursive dependencies are also being used a for packages starting with `ament_lint_*` a single test dependency is
+sufficient to test with a set of common linters.
+
+``package.xml``:
+
+.. code:: xml
+
+    <test_depend>ament_lint_auto_py</test_depend>
+
+    <!-- this recursively depends on a set of common linters -->
+    <test_depend>ament_lint_common_py</test_depend>
+
+
+How to exclude linter modules with ament_lint_auto_py?
+------------------------------------------------------
+
+Linter modules can be excluded via the pytest configurable variables `ament_lint_auto_exclude` in pytest config files like `pytest.ini` or `pyproject.toml`.
+
+As an example to exclude the `copyright` linter:
+
+.. code::
+    [pytest]
+
+    ament_lint_auto_exclude = ament_copyright
+
+
+How to exclude files with ament_lint_auto_py?
+---------------------------------------------
+
+Linter hooks shall conform to the ament_lint_auto_py convention of excluding files
+specified in the environment list variable `ament_lint_auto_file_exclude`.
+
+.. code::
+    [pytest]
+
+    ament_lint_auto_file_exclude = /path/to/ignored_file
+
+For a more specific example, this excludes all python files matching a pattern using globbing.
+Multiple expressions can be combined on multiple lines.
+
+
+.. code::
+    [pytest]
+
+    ament_lint_auto_file_exclude = 
+        src/*
+        test/*.cpp
+
+How to register 3rd party linters with ament_lint_auto_py?
+---------------------------------------------------------
+
+To register a third party linter implement class like the following.
+
+.. code:: python
+
+  class CustomRunner:
+
+      NAME = 'ament_custom'
+      FILE_TYPES = ('*.py',)
+
+      def __init__(self, args: list[str]) -> None:
+          self.args = args
+
+      def __call__(self) -> Literal[0, 1]:
+          return main(self.args)
+
+  def main():
+    # Custom linting
+    pass
+
+Then in a `setup.py` register an entry point for the `CustomRunner`.
+
+.. code:: python
+
+  entry_points={
+      'ament_lint': [
+          'ament_lint_cmake = ament_lint_cmake.main:LintCMakeRunner'
+      ]
+  },

+ament_lint_common_py
+====================
+
+The pytest variant of ament_lint_common. The dependencies match to keep parity between them.
+
+A mechanism for running the following set of common linters:
+
+* `ament_copyright <https://github.com/ament/ament_lint/blob/master/ament_copyright/doc/index.rst>`_ : a copyright linter which checks that copyright statements and license headers are present and correct
+
+* `ament_cppcheck <https://github.com/ament/ament_lint/blob/master/ament_cppcheck/doc/index.rst>`_ : a C++ checker which can also find some logic tests
+
+* `ament_cpplint <https://github.com/ament/ament_lint/blob/master/ament_cpplint/doc/index.rst>`_ : a C++ style checker (e.g. comment style)
+
+* `ament_flake8 <https://github.com/ament/ament_lint/blob/master/ament_flake8/doc/index.rst>`_ : a style checker for Python files
+
+* `ament_cmake_lint <https://github.com/ament/ament_lint/blob/master/ament_cmake_lint/doc/index.rst>`_ : a cmake linter
+
+* `ament_pep257 <https://github.com/ament/ament_lint/blob/master/ament_pep257/doc/index.rst>`_ : a style checker for Python docstrings
+
+* `ament_uncrustify <https://github.com/ament/ament_lint/blob/master/ament_uncrustify/doc/index.rst>`_ : a C++ style checker
+
+* `ament_xmllint <https://github.com/ament/ament_lint/blob/master/ament_xmllint/doc/index.rst>`_ : an xml linter
+
+The `ament_lint_auto_py <https://github.com/ament/ament_lint/blob/master/ament_lint_auto_py/doc/index.rst>`_ documentation provides information on using ament_lint_common_py.
