Deploy with Gulp

You can easily deploy your site build to a gh-pages branch. First, follow the instructions at gulp-gh-pages to get your branch prepared for the deployment and to install the module. Then, in gulpfile.js you'll want to include something like the code below. gulp.src() needs to be the path to your final site folder, which by default will be _site. If you change the destination in your _config.yml file, be sure to reflect that in your gulpfile.

var deploy = require("gulp-gh-pages");

gulp.task("deploy", ["jekyll-build"], function () {
    return gulp.src("./_site/**/*")
        .pipe(deploy());
});
