Piwik is self-hosted software. You need to install and configure Piwik
separately. Piwik needs PHP and a MySQL database to store data on site visits.
<p>For more details, see <a href="http://piwik.org/">http://piwik.org/</a>
<p>This plugin embeds the Piwik (Javascript) tracking code in the theme footer.
To install the plugin, unpack under the \'/user/plugins\' directory in your
Habari installation.
Then activate and configure the plugin from the dashboard (Admin-Plugins).
<p>The configuration options are:
<ul>
<li>Pwiki site URL: This is the full URL of the Piwik site (e.g. \'http://www.example.com/piwik\') - the trailing slash \'/\' is required.</li>
<li>Piwik site number: Piwik can track multiple Web sites. The site number is displayed in the Piwik-Settings administration screen under the \'Site\' tab in the \'ID\' field.</li>
<li>Tracked logged-in users: Visits by logged in users can optionally be ignored.</li>
<li>Auth Token: Your API "token_auth" to allow retrieval of stats for dashboard modules.</li>
</ul>';
