<h3><label for="title">Before Using This Plugin</label></h3>

<p class="postbox-container">To use the WP SoundCloud Ultimate plugin you will firstly need to create a SoundCloud app using your current SoundCloud account details and then paste some
of the details from your app in the configuration settings of this page.
<br /> 
<h2>Creating Your SoundCloud App</h2>
This literally takes a minute to do. To create a SoundCloud app go to <a href="http://soundcloud.com/you/apps" target="_blank">THIS PAGE</a> and fill in the details as follows:
<ol>
	<li type="disc">
		Enter the following string for the name of your app - <strong>soundcloud-ultimate-plugin</strong></li>
	<li type="disc">
		Then click the register button and enter the following details in the app form:
		<ol>
		<li type="disc"><strong>Website of your app</strong> - Enter your own website URL</li>
		<li type="disc"><strong>Redirect URI for Authentication</strong> - Copy and paste the following url - <span style="color: green; background-color:yellow;"><strong><?php echo site_url();?>/wp-admin/admin.php?page=wpshq_scu_plugin_options</strong></span></li>
		</ol>
	</li>
</ol>
<h2>Configuring the Plugin</h2>
After creating the app, copy the following details from your app and paste in the configuration settings on this page:
<ol>
	<li type="disc"><strong>Sound Cloud Client ID</strong> - Copy this value from your SoundCloud app and paste in the field below.</li>
	<li type="disc"><strong>Sound Cloud Client Secret</strong> - Copy this value from your SoundCloud app and paste in the field below.</li>
</ol>
After entering the configuration settings click the "Save Settings" button.
<h2>Connecting To SoundCloud</h2>
After saving your settings click the "<strong>Connect To Soundcloud</strong>" link in the "SoundCloud Connection Status" section below.
This will take you to the SoundCloud site and ask you to allow the "soundcloud-ultimate-plugin" to connect to your SoundCloud account.
Click the "Connect" button.
