<!DOCTYPE html><!-- This page is a placeholder for generated extensions api doc. Note:
1) The <head> information in this page is significant, should be uniform
across api docs and should be edited only with knowledge of the
templating mechanism.
3) All <body>.innerHTML is genereated as an rendering step. If viewed in a
browser, it will be re-generated from the template, json schema and
authored overview content.
4) The <body>.innerHTML is also generated by an offline step so that this
page may easily be indexed by search engines.

This documentation tells you how to write extensions
and packaged apps for the
<a href="http://www.google.com/chrome">Google Chrome browser</a>.
Because extensions came first,
the APIs and these docs say <em>extension</em> everywhere.
</p>
<p class="caution">
<b>Note:</b>
Unless you see a note
describing an exception for packaged apps,
everything in this documentation applies to both extensions and packaged apps.
</p>
<h2 id="readme"> Where to start </h2>
<p>
Before you code,
read these:

<dd> Build a simple "Hello, World" extension in about 5 minutes </dd>
<dt> <a href="overview.html">Overview</a> </dt>

In general, you should view these pages at

(for example,
<a href="http://code.google.com/chrome/extensions/overview.html">http://code.google.com/chrome/extensions/overview.html</a>).
However, if you need to see the very latest doc
or you're using a different version of Google Chrome
than most of the world is
(perhaps the <a href="http://dev.chromium.org/getting-involved/dev-channel">Dev channel</a>),
you might want to use a different URL
(for example,
<a href="http://code.google.com/chrome/extensions/dev/overview.html">.../extensions/<b>dev/</b>overview.html</a>).
The following table lists the doc locations and explains how they differ.
</p>
<p>

<tbody><tr>
<th> URL </th> <th> Version </th>

<tr>
<td>
<a href="http://code.google.com/chrome/extensions/overview.html">.../extensions/...</a>

or if you're curious about features to come.
