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.";
