Like most other WordPress plugins, you can install the Mowser plugin by unpacking the distributed plugin file in the wp-content/plugins directory of your WordPress installation. Once unpacked you should see a "Mowser Plugin" entry in the "Plugins" tab of your administrative interface for WordPress. You'll need to use the "Activate" link under Plugin Management to start using the plugin.

As soon as the plugin is active it will start redirecting mobile users to the Mowser version of your blog. You can test this on your own phone by entering the URL for your blog into your mobile browser. Or if you don't have a phone that you can test web pages from you can try using the OperaMini Simulator:

The Mowser site will detect if you're using Google AdSense on your existing site and swap to Google AdSense for Mobile automatically. It also supports using advertising from AdMob on the mobile pages.

You can find a selection of handheld stylesheets for wordpress themes at the Mowser publisher wiki:

If you use Widgets to configure your sidebar you can use the Mowser Widget to promote your mobile version. Once you have the Mowser plugin enabled just drag the widget into your sidebar and save the changes.
