+## Filters
+
+If you want to exclude some Permalink to processed with the plugin so, just add the filter looks like this:
+```
+function check_xml_sitemap_url( $permalink ) {
+  if ( false !== strpos( $permalink, 'sitemap.xml' )) {
+    return '__true';
+  }
+  return;
+}
+add_filter( 'custom_permalinks_request_ignore', 'check_xml_sitemap_url' );
+```
+
+If you want to exclude permalink from any post type so, use `custom_permalinks_exclude_post_type` filter.
+
+`custom_permalinks_exclude_post_type` filter looks like this:
+```
+function yasglobal_exclude_post_types( $post_type ) {
+  if ( $post_type == 'custompost' ) {
+    return '__true';
+  }
+  return '__false';
+}
+add_filter( 'custom_permalinks_exclude_post_type', 'yasglobal_exclude_post_types');
+```
+Note: `custom_permalinks_exclude_post_type` doesn't work on the posts permalink which has been created previously.
+
