bbPress

Add the entire hot-tags-plus directory to bbPress' my-plugins/ directory.

It is recommended but optional to create a caching directory, chmod 777. It should be located above your "web root" if posible for added security.

Edit the settings at the top of the plugin with the caching directory, etc.

Edit your templates as desired to display the new Hot Tags.

You can replace bbPress's bb_tag_heat_map() with hot_tags_plus() within the front-page.php template and bb_tag_heat_map() within tags.php template.

There are many options you can use, here is an example of how it's done: ` 13, 'largest' => 34, 'unit' => 'px', 'limit' => 40, 'minimum' => 2, 'maximum'=>0, 'colors' => array('24244C','600000','C00000')); hot_tags_plus($options); ?>
