return "## Can't we simplify? \n\nBecause running websites and managing databases isn't always worth the effort, \"Static Content Generators\" like [Dr. jekyll](http://jekyllrb.com/) and [Mr. Hyde](http://hyde.github.io/) have begun to gain traction as people pre-build websites and then place the static HTML results onto their server. \n\nThis means the web server doesn't need to be configured with any special software or databases - it simply serves the generated static HTML files.\n\nHowever, you still have to install the generator and setup a \"build\" process of sorts after every article.\n\n## Meet Jr.\n\n`Jr` is a truly *static*, static content generator. All the processing of your files happens on the requesting client's computer as needed. The whole system is written in client-side JavaScript. This means:\n\n- minimal bandwidth requirements\n- better search engine indexing\n- awesome screen reader support\n- *zero* security vulnerabilities\n- and more!\n\nHowever, the neatest thing about `Jr` is that you don't have to configure, setup, or install _anything_! Simply download the files, create your articles, and upload everything to your server!\n\ndone.";
