It does not overload the load->view() methods, that would be bad. You need to update your controllers to use the syntax and methods of the template in each instance that you want to use:

In most cases, you use $this->template->build() instead of $this->load->view() , after creating your template, defining regions, setting headers, etc.
The examples should include the user guide included with your download.
