+### Can my javascript code have increased indentation?
+
+It depends on the version of eslint you're using.
+
+[indent](https://eslint.org/docs/rules/indent) rule in `eslint@3.x` makes it possible, but if you use `eslint@4.x` be aware that this rule has been rewritten and is more strict now, thus it doesn't allow to have increased initial indentation.
+
+You can however use [indent-legacy](https://eslint.org/docs/rules/indent-legacy) rule instead.
+More informations [here](https://eslint.org/docs/user-guide/migrating-to-4.0.0#indent-rewrite).
