    <para>
        The <classname>Zend_Service_SlideShare</classname> component is used to interact with the
        <ulink url="http://www.slideshare.net/">slideshare.net</ulink> web services for hosting
        slide shows online. With this component, you can embed slide shows which are hosted on this
        web site within a web site and even upload new slide shows to your account.

        <title>Getting Started with Zend_Service_SlideShare</title>

        <para>
            In order to use the <classname>Zend_Service_SlideShare</classname> component you must first create an account
            on the slideshare.net servers (more information can be found
            <ulink url="http://www.slideshare.net/developers/">here</ulink>) in order to receive an
            API key, username, password and shared secret value -- all of which are needed in order
            to use the <classname>Zend_Service_SlideShare</classname> component.
        </para>

        <para>
            Once you have setup an account, you can begin using the
            <classname>Zend_Service_SlideShare</classname> component by creating a new instance of the
            <classname>Zend_Service_SlideShare</classname> object and providing these values as shown below:
