4This documentation tells you how to write extensions
5and packaged apps for the
6<a href="http://www.google.com/chrome">Google Chrome browser</a>.
7Because extensions came first,
8the APIs and these docs say <em>extension</em> everywhere.

11<p class="caution">
12<b>Note:</b>
13Unless you see a note
14describing an exception for packaged apps,
15everything in this documentation applies to both extensions and packaged apps.

59In general, you should view these pages at
60<b>http://code.google.com/chrome/extensions/<em>&lt;filename></em></b>
61(for example,
62<a href="http://code.google.com/chrome/extensions/overview.html">http://code.google.com/chrome/extensions/overview.html</a>).
63However, if you need to see the very latest doc
64or you're using a different version of Google Chrome
65than most of the world is
66(perhaps the <a href="http://dev.chromium.org/getting-involved/dev-channel">Dev channel</a>),
67you might want to use a different URL
68(for example,
69<a href="http://code.google.com/chrome/extensions/dev/overview.html">.../extensions/<b>dev/</b>overview.html</a>).
70The following table lists the doc locations and explains how they differ.
