-            -
            **Note:** If you don't know about filters & actions, please read the official [WordPress Plugin API](https://codex.wordpress.org/Plugin_API).
-            -
            **Filter: wp404arsp/init**
-            -
            This filter is applied at the initialization of the plugin, in the `template_redirect` action.
-            -
            By default, `$init = true` which means that the plugin will take action when a 404 is about to be displayed. If is set to `false`, then le plugin will stop it's initialization.
-            -
            The second argument: `$request_uri` is the requested URI sent to the browser.
-            -
            Returning `$init` as a boolean is **mandatory**.
-            -
            Usage example:
+            `
-            -
            add_filter('wp404arsp/init', 'my_404_no_init', 10, 2);
-            -
            function my_404_no_init($init, $request_uri){
-            -
                if($request_uri == 'https://www.my-website.com/custom-page')
-            -
                    $init = false;
-            -
                return $init;
+            }
-            -
            `
-            -
            **Filter: wp404arsp/redirect**
-            -
            This filter is applied right before the plugin sends a redirection. You can use it to set a custom behavior depending on multiple factors.
-            -
            The array's key `$args['url']` will be used as the redirection's URI.
-            -
            If the key `$args['url']` is set to `false`, the plugin's fallback behavior will be bypassed and the default 404 page will be displayed.
-            -
            The second argument: `$settings` is an array of the plugin's settings.
-            -
            Returning an `$args` array is **mandatory**.
