This section is related to the configuration. You can see a sample here. You can leave all the portlet's preferences as blank, that means the default value will be taken and you do not need to care about it at this time.
Like portal.xml, you can define the layout for each page in your site as shown in the following example:
<!-- ... -->
<portlet-application> <!-- A custom document for content and SCV portlet to display -->
</portlet-application>
<portlet-application> <!-- A CLV portlet with a custom template. -->
</portlet-application>
<portlet-application> <!-- A CLV portlet with another custom template. -->
</portlet-application>
<!-- ... -->
