Download the latest release of Joose from the downloads page. We currently only upload stable releases, so you can just grap the latest and greatest.
Copy the file joose.js or joose.mini.js to your application's JavaScript directory and include it in your html pages with something like:
<script type="text/javascript" src="/path/to/joose.js"></script>
The file joose.mini.js is the same as the file joose.js. The only difference is removed white space and comments which reduces the file size and improves page loading time. We recommend using joose.js in development and joose.mini.js in production systems. There also extra files whithe the .gz extention. These are packed for even smaller file sizes. If your web-server supports using these compressed files, it will improve load time even more.
For some functionality you will also need the JavaScript JSON library which you can obtain JSON.org
