4  Extensions are small software programs that
5  can modify and enhance the functionality of the Chrome browser.
6  You write them using web technologies such as
7  HTML, JavaScript, and CSS.

17  Extensions have little to no user interface.
18  For example, the image to the right shows the icon
19  that provides the UI for the
20  <a href="samples#google-mail-checker">Google Mail Checker extension</a>.

24  Extensions bundle all their files
25  into a single file that the user downloads and installs.
26  This bundling means that, unlike ordinary web apps,
27  extensions don't need to depend
28  on content from the web.

32  You can distribute your extension
33  using the
34  <a href="https://chrome.google.com/webstore/developer/dashboard">Chrome Developer Dashboard</a>
35  to publish to the
36  <a href="http://chrome.google.com/webstore">Chrome Web Store</a>.
37  For more information, see the
38  <a href="http://code.google.com/chrome/webstore">store developer documentation</a>.
