+
+How to make it read RSS?
+
+First, we need to load the RSS :
+
+    $rss = SRSS::read('http://exemple.com/rss.xml');
+
+Easy, right? Then you can extract general informations :
+
+    echo $rss->title; // will display blog title
+
+Then, you can take care of articles. You can select a precise article :
+
+    $article1 = $rss->getItem(1); // or $rss->getFirst();
+
+Or looping them :
+
+    foreach($rss as $article)
+    {
+		echo '<a href="'.$article->link.'">'. SRSSTools::formatDate('d/m/y', $item->pubDate).' '.$item->title.'';
+    }
+
+If you like arrays, you can transform the RSS into an array :
+
+    $rssArray = $rss->toArray();
+
+You can also save it into your server with :
+
+    $rss->save('/www/rss/rss.xml'); // example
+	
+----------------------------------
+
+How to make it create RSS?
+
+First, we need to initialize the RSS :
+
+    $rss = SRSS::create();
+
+Easy, right? Then you can add general informations :
+
+    $rss->title = 'My Awesome Blog';
+    $rss->link = 'http://shikiryu.com/devblog/';
+    $rss->description = 'is awesome';
+
+Those 3 are mandatory to validate your RSS, other options can be added.
+Then, you can add articles. Let's imagine $content contains an array from your database.
+
+    foreach($content as $item){
+		$rssitem= new SRSSItem; // we create an item
+		$rssitem->title = $item["title"]; // adding title (option)
+		$rssitem->link = $item['link']; // adding link (option)
+		$rssitem->pubDate = $item["date"]; // date automatically transformed into RSS format (option)
+		$rssitem->description = $item["text"]; // adding description (mandatory)
+		$rss->addItem($rssitem); // we add the item into our RSS
+    }
+
+There are 2 functions to add item.
+The first one will add items in the order you enter them, from top to bottom.
+
+    $rss->addItem($item);
+
+The other one does the opposite and add the next item in top of your RSS
+
+    $rss->addItemBefore($item);
