How to enable RSS feed in LE 9.2.6

I want to show RSS feed link on the main screen, I am using transparency skin folder I saw this in Home.xml file :

</control>
            <include condition="system.getbool(lookandfeel.enablerssfeeds)">RSS</include>
        </control>

but don't know how to show it on Home screen?

Thanks,

I enable it from skin interface but I can't change it from RssFeeds.xml file under useraddon folder!

I add rss feed link but didn't take effect with me!
