Creating widget or sidebar blocks?

[qpurser]

I found some coding I would like to use in a widget or sidebar block.
They were in the "Style Manager" -> "vBulletin CMS templates".
For example this one:
vbcms_widget_myfriends_page
code:
<div class="cms_widget">
<div class="block">
<div class="cms_widget_header widget_header">
<h3>{vb:rawphrase friend_activity}</h3>
</div>
<div class="cms_widget_content widget_content">
{vb:raw friends_html}
</div>
</div>
</div>

How can I make this work as a widget or sidebar block?

Thanks for any help
