+## Usage

 After plugin activation, you can use Nette Latte templates in your theme. Just use `.latte` file extension instead of `.php`. Template files with `.php`  extension will continue to work, but that templates will have lower priority in template resolution.
 
 There are limitations with `header.php` and `footer.php`. You should use instead `{php wp_head()}` and `{php wp_footer()}` macro inside layout file. If you need to use header.php and footer.php file (e.g. for WooCommerce plugin), leave that files blank.

-if (class_exists('NetteLatteEngine\NetteLatteEngine')) {
