+    """
+    Build up performance testing documentation dynamically by combining
+    text data from YAML files that reside in `perfdoc` folders
+    across the `testing` directory. Each directory is expected to have
+    an `index.rst` file along with `config.yml` YAMLs defining what needs
+    to be added to the documentation.
+
+    The YAML must also define the name of the "framework" that should be
+    used in the main index.rst for the performance testing documentation.
+
+    The testing documentation list will be ordered alphabetically once
+    it's produced (to avoid unwanted shifts because of unordered dicts
+    and path searching).
+
+    Note that the suite name headings will be given the H4 (---) style so it
+    is suggested that you use H3 (===) style as the heading for your
+    test section. H5 will be used be used for individual tests within each
+    suite.
+
+    Usage for verification: "./mach lint -l perfdocs ."
+    Usage for generation: "./mach lint -l perfdocs --fix ."
+
+    For validation, see the Verifier class for a description of how
+    it works.
+
+    The run will fail if the valid result from validate_tree is not
+    False, implying some warning/problem was logged.
+
+    :param dict config: The configuration given by mozlint.
+    :param StructuredLogger logger: The StructuredLogger instance to be used to
+        output the linting warnings/errors.
+    :param list paths: The paths that are being tested. Used to filter
+        out errors from files outside of these paths.
+    :param bool generate: If true, the docs will be (re)generated.
