Where is the template for the promoted to front page items? I want to add some elements and icons into the promoted items template but I can't find where this template is located.

For example, right now my page is rendering:

&lt;article id="node-62" class="node node-blog node-promoted node-teaser contextual-links-region clearfix" about="/sites/sample/content/sample" typeof="sioc:Post sioct:BlogPost"&gt;
  &lt;h2 property="dc:title" datatype=""&gt;&lt;a href="/sites/sample/content/sample"&gt;Sample&lt;/a&gt;&lt;/h2&gt;
  &lt;div class="submitted"&gt;
    //blah blah blah
  &lt;/div&gt;
  &lt;div class="content"&gt;
    //blah blah blah
  &lt;/div&gt; 
&lt;/article&gt;


Instead, I would like to add things like:

&lt;article id="node-62" class="node node-blog node-promoted node-teaser contextual-links-region clearfix" about="/sites/sample/content/sample" typeof="sioc:Post sioct:BlogPost"&gt;
  &lt;i class="icon-menu"&gt;&lt;/i&gt;
  &lt;div class="something"&gt;Maybe some other stuff&lt;/div&gt;
  &lt;h2 property="dc:title" datatype=""&gt;&lt;a href="/sites/sample/content/sample"&gt;Sample&lt;/a&gt;&lt;/h2&gt;
  &lt;div class="submitted"&gt;
    //blah blah blah
  &lt;/div&gt;
  &lt;div class="content"&gt;
    //blah blah blah
  &lt;/div&gt; 
&lt;/article&gt;


Or anything else I want in the future.
This is tipically done in node.tpl.php in your theme. Just keep in mind that this template works for any node, so you should introduce some logic to check if the node is promoted, e.g.

&lt;?php if ($node-&gt;promoted) { ?&gt;
  &lt;i class="icon-menu"&gt;&lt;/i&gt;
  &lt;div class="something"&gt;Maybe some other stuff&lt;/div&gt;
&lt;?php } ?&gt;
