Plugin Overrides ================ Override HTTP Content Security Policy ------------------------------------- If you would like to replace the default HTTP Content Security Policy header, you can use the method `setContentSecurityPolicy()`: ```php setContentSecurityPolicy(array('script-src' => 'something')); } } ``` Template Overrides ------------------ Any templates defined in the core can be overrided. By example, you can redefine the default layout or change email notifications. Example of template override: ```php $this->template->setTemplateOverride('header', 'theme:layout/header'); ``` The first argument is the original template name and the second argument the template to use as replacement.
