    document.querySelector('.progress-bar').style.marginRight = '10px'

    var msg = document.createElement('span');
    var text = document.createTextNode(' ' + pointsCount + ' points!');
    msg.appendChild(text);

    var projectHeader = document.querySelector(".js-project-header h3");

    projectHeader.appendChild(msg);
}();

points should be added as labels with the following format: "points: 1" where 1 represents the number of points for each issue
