-**I'm [looking for contributors](https://github.com/jorisroovers/gitlint/issues/134) that are interested in taking a more active co-maintainer role as it's becoming increasingly difficult for me to find time to maintain gitlint. Please leave a comment in [#134](https://github.com/jorisroovers/gitlint/issues/134) if you're interested!**
