Recent versions of gulp-iconfont emit a glyphs (or codepoints < 4.0.0) event (see docs) which should likely be used instead of the workflow described below. However, it will continue to work as expected. The future of this plugin will be discussed in https://github.com/backflip/gulp-iconfont-css/issues/9. Then, add it to your gulpfile.js. Important: gulp-iconfont-css has to be inserted before piping the files through gulp-iconfont.
