<p>Create your own category-controlled ‘Top Tip’ to display next to relavant posts.<br />
Display you favourite top tip next to a post with the same category. If you have more than one tip in the matching category the chosen top tip will be a random selection from all within that category. It’s also possible to specify the top tip by id in a shortcode. An optional feature is to add a link to another post containing further information about your Top Tip.</p>
<h3>From within WordPress</h3>
<ol>
<li>Visit Plugins -> Add New</li>
<li>Search for ‘Top Tips’</li>
<li>Activate Top Tips from your Plugins page</li>
</ol>
<h3>Manually</h3>
<ol>
<li>Upload the directory <code>top-tips</code> to the <code>/wp-content/plugins/</code> directory.</li>
<li>Activate the plugin through the ‘Plugins’ menu in WordPress.</li>
<li>Set the colours and icon via Top Tips > Top Tips Settings.</li>
<li>Create some new top tips and assign them to one or more categories.</li>
<li>Add the shortcode [top-tips] to your posts or in a template file <code><?php echo do_shortcode('[top-tips]'); ?></code>.</li>
<li>Remember your post needs to be assigned to the same category as the Top Tip for the tip to display.</li>
</ol>

<h4>How to Use</h4>
<p>To define a tooltip  (new, easy way):  Click the tooltip icon on your visual content editor to add the tooltip shortcode. Change the content attribute to whatever you want to be the content inside the tooltip bubble. Change the tooltip trigger to whatever content you want to be used to trigger the tooltip, when hovered. (see screenshots)</p>
