 * Describe the brief of the change. The sentence should end with a punctuation.
 * If this is a breaking change, mark it with `**(Breaking)**`.
 * At the end of the entry, add an implicit link to your GitHub user page as `([@username][])`.
-* Alternatively, you may modify the CHANGELOG.md file directly, but this may result in conflicts later on. Also, if this is your first contribution to RuboCop project, add a link definition for the implicit link to the bottom of the changelog as `[@username]: https://github.com/username`.
