 <p>If you're making changes to <code>OxJS</code> (methods, widgets, modules, etc.), make them in <code>source/</code>, not in <code>dev/</code>. <code>dev/</code> contains symlinks to <code>source/</code> (plus some json files to tell <code>Ox.load</code> which resources to include), so your edits will be live.</p>
 
 <p>To add or remove files, or to rebuild the production version, run <code>/tools/build/build.py</code>. This will update both <code>build/</code> and <code>dev/</code> from <code>source/</code>.</p>
