+## WebStorm
+
+WebStorm has built-in support for ESLint issue reporting. Auto fixing is only supported in versions 2016.3 and newer.
+
+To enable ESLint reporter, [follow the guide][webstorm-eslint] on WebStorm's support page.
+To use the new autofix feature, [read their blog post][webstorm-eslint-autofix] on the topic.
+
+> The autofix feature must be manually triggered, ie. no autofix-on-save. However, this is still much better than fixing all the issues by hand... ✍️
