It’s an easy way to show and order all posts from category/tag into a page/post. Really handy for showing your tutorials, articles, etcetera. 
It shows as a list(<ul><li>) so it will apply your blog style-sheet as you wish.
Note: If the selected term(category or tag) has a description, it will be shown in a <blockquote> tag.
To see it in action click <a href="http://felipetonello.com/blog/tutoriais-e-artigos/" title="Felipe Tonello blog" rel="nofollow ugc">here</a>.
Usage:
<ol>
<li>
Go to Category Show’s options page and generate the tag.
</li>
<li>
Insert your new tag into your post.
</li>
</ol>
Tags to know:
If you want to apply some CSS, those are the tags you should know: <h3>, <ul>, <li>, <a> and <blockquote>.
Output example:
<pre><code><h3>Category</h3>
<blockquote>Category description, if exists</blockquote>
<ul>
<li><a title="link title" rel="bookmark" href="link">title</a></li>
</ul>
</code></pre>
That’s it!
