+ESLint
+======
+
+`ESLint`_ is a popular linter for JavaScript.
+
+Run Locally
+-----------
+
+The mozlint integration of `ESLint`_ can be run using mach:
+
+.. parsed-literal::
+
+    $ mach lint --linter eslint <file paths>
+
+Alternatively, omit the ``--linter eslint`` and run all configured linters, which will include
+ESLint.
+
+
+Configuration
+-------------
+
+The `ESLint`_ mozilla-central integration uses a blacklist to exclude certain directories from being
+linted. This lives in ``topsrcdir/.eslintignore``. If you don't wish your directory to be linted, it
+must be added here.
+
+The global configuration file lives in ``topsrcdir/.eslintrc``. This global configuration can be
+overridden by including an ``.eslintrc`` in the appropriate subdirectory. For an overview of the
+supported configuration, see `ESLint's documentation`_.
+
+
+ESLint Plugin Mozilla
+---------------------
+
+In addition to default ESLint rules, there are several Mozilla-specific rules that are defined in
+the :doc:`Mozilla ESLint Plugin <eslint-plugin-mozilla>`.
