 Features:
 - **No configuration.** Which means no decisions to make, nothing to argue about and no special files to manage.   
-While this might sound extreme, keep in mind that `ktlint` tries to capture (reflect) **official code style** from [kotlinlang.org](https://kotlinlang.org/docs/reference/coding-conventions.html) and [Android Kotlin Style Guide](https://android.github.io/kotlin-guides/style.html)
+While this might sound extreme, keep in mind that `ktlint` tries to capture (reflect) **official code style**[*](https://github.com/shyiko/ktlint/issues/284#issuecomment-425177186) from [kotlinlang.org](https://kotlinlang.org/docs/reference/coding-conventions.html) and [Android Kotlin Style Guide](https://android.github.io/kotlin-guides/style.html)
 (+ [we respect your .editorconfig](#editorconfig) and support additional [ruleset](#creating-a-ruleset)|s).
 - **Built-in formatter.** So that you wouldn't have to fix all style violations by hand.
 - **Customizable output.** `plain` (+ `plain?group_by_file`), `json` and `checkstyle` reporters are available out-of-the-box.
