+### 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 `[email protected]` makes it possible, but if you use `[email protected]` be aware that this rule has been rewritten and is more strict now, thus it doesn't allow to have increased initial indentation.
