How do I use promises in NodeJS?

routes.js

/*
 * This is a NodeJS app using the official MailChimp API wrapper.
 * I want to grab this data and display it in a custom view, but without a giant callback-y mess. Ideas?
 */

exports.view = function(req, res){
  mc.campaigns.list({campaign_id: req.params.id}, function(campaignData) {
    var campaign = campaignData.data[0];
    mc.reports.summary({cid:req.params.id}, function(reportData) {
      mc.lists.list({ list_id: campaignData.list_id }, function(listData) {
        mc.reports.clicks({ cid:req.params.id }, function(clickData){
          // I also want to hit another endpoint to grab details about unsubscribes/reasons before returning.
          res.render('reports/view', { title: 'Report for ' + campaign.title, campaign: campaign, report:reportData, list:listData.data[0], clicks:clickData });
        });
      });
    }, function (error) {
      console.log(error);
      if (error.name == "Campaign_DoesNotExist") {
        req.session.error_flash = "The campaign does not exist";
      } else if (error.error) {
        req.session.error_flash = error.code + ": " + error.error;
      } else {
        req.session.error_flash = "An unknown error occurred";
      }
      res.redirect('/reports');
    });
  });
};
