Display custom text if there is no comments I want to display custom text on a node if there is no comments yet.
I think i should check for comments count in preprocess_node, and somehow add the text below Comments title.

function MYTHEME_preprocess_node(&amp;$variables, $hook) {
  if($variables['comment_count'] === '0') {
     //somehow i need to display text - There is not comments yet
  }
}


How can achieve this? here is an example of how it should looks like:



EDIT:
Also i have found better solution, may be useful for someone.
(using Zen theme - aka STARTERKIT modified)
I have added comments-wrapper.tpl.php

And in a template.php added preprocess function of this wrapper

function MYTHEME_preprocess_comments_wrapper(&amp;$variables) {
    $variables['MYTHEME_comment_title'] = t('Comments');
      $commented_node = $variables['node'];

      if(!empty($commented_node) &amp;&amp; is_object($commented_node)){
        $comment_count = 0;
        if(isset($commented_node-&gt;comment_count)){
          $comment_count = $commented_node-&gt;comment_count;
        }
        $variables['MYTHEME_comment_title'] = format_plural($comment_count, '1 comment', '@count comments');
         if($comment_count == 0) {
            $variables['MYTHEME_comment_title'] = t('Comments');
            $variables['empty_comments'] = t('There is no comments yet');
     }
}


And in a comments-wrapper.tpl.php i have printed out $empty_comments variable

  &lt;?php print $empty_comments; ?&gt;
In your node.tpl.php you could check the $comment_count variable to see if there are comments. If so, render the comments, if not display your alternet text.

Example:

&lt;?php if ($comment_count &gt; 0 ): ?&gt;
  &lt;?php print render($content['comments']); ?&gt;
&lt;?php else: ?&gt;
        &lt;strong&gt; 0 comments yet&lt;/strong&gt;
        &lt;?php echo l('Be the first','commentpath'); ?&gt;
&lt;?php endif; ?&gt;
