1. IMPORTANT! If you are upgrading from a previous version first deactivate the plugin, then delete the plugin folder from your server.

2. If you have the Similar Posts Feed plugin installed you must deactivate it before installing Similar Posts (which now does the same job).

3. Upload the plugin folder to your /wp-content/plugins/ folder. If you haven't already you should also install the Post-Plugin Library>.

4. Go to the Plugins page and activate the plugin.

5. Put <?php similar_posts(); ?> at the place in your template where you want the list of related posts to appear or use the plugin as a widget.

6. Use the Options/Settings page to adjust the behaviour of the plugin.
