+Stylelint
+=========
+
+`Stylelint`__ is a popular linter for CSS.
+
+Run Locally
+-----------
+
+The mozlint integration of Stylelint can be run using mach:
+
+.. parsed-literal::
+
+    $ mach lint --linter stylelint <file paths>
+
+Alternatively, omit the ``--linter stylelint`` and run all configured linters, which will include
+Stylelint.
+
+Stylelint also supports the ``--fix`` option to autofix most errors raised from most of the rules.
+
+See the `Usage guide`_ for more options.
+
+Understanding Rules and Errors
+------------------------------
+
+* Only some files are linted, see the :searchfox:`configuration <tools/lint/stylelint.yml>` for details.
+
+  * By design we do not lint/format reftests not crashtests as these are specially crafted tests.
+
+* If you don't understand a rule, you can look it in `stylelint.io's rule list`_ for more
+  information about it.
+
+Common Issues and How To Solve Them
+-----------------------------------
+
+This code should neither be linted nor formatted
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+* If it is a third-party piece of code, please add it to :searchfox:`ThirdPartyPaths.txt <tools/rewriting/ThirdPartyPaths.txt>`.
+* If it is a generated file, please add it to :searchfox:`Generated.txt <tools/rewriting/Generated.txt>`.
+* If intentionally invalid, please add it to :searchfox:`.stylelintignore <.stylelintignore>`.
+
+Configuration
+-------------
+
+The global configuration file lives in ``topsrcdir/.stylelintrc.js``.
+For an overview of the supported configuration, see `Stylelint's documentation`_.
+
+Please keep differences in rules across the tree to a minimum. We want to be consistent to
+make it easier for developers.

+
+Stylelint task
+^^^^^^^^^^^^^^
+
+This is a tier-1 task. For test failures the patch causing the
+issue should be backed out or the issue fixed.
+
+Some failures can be fixed with ``./mach lint -l stylelint --fix path/to/file``.
+
+For test harness issues, file bugs in Developer Infrastructure :: Lint and Formatting.
