        |Hi @${username}!
        |
        |Thanks for wanting to contribute to Bootstrap by sending this pull request!
        |Unfortunately, your pull request seems to have some problems:
        |${messagesMarkdown}
        |
        |You'll need to **fix these mistakes** and revise your pull request before we can proceed further.
        |Once you've fixed these problems, you can either ask the maintainers to re-open this pull request, or you can create a new pull request.
        |Thanks!
        |
        |(*Please note that this is a [fully automated](https://github.com/twbs/rorschach) comment.*)
