+/**
+ * Performs server side tracking for AI bots.
+ *
+ * Normal server side tracking: when no caching plugins or CDNs are being
+ * used, this class will send tracking requests in the wp_footer hook.
+ *
+ * When advanced-cache.php is used: when a caching plugin creates an
+ * advanced-cache.php file that WordPress uses, tracking must be done
+ * through the standalone script in misc/track_ai_bot.php. This script
+ * must be manually added to a user's wp-config.php file, right after
+ * ABSPATH is defined.
+ *
+ * When .htaccess is used: when a caching plugin modifies the .htaccess
+ * to serve cached files directly, AI bot tracking is not possible.
+ *
+ * When a CDN is used: when a CDN is used to serve cached content, AI
+ * bot tracking can be accomplished through the use of ESI (Edge Side Includes).
+ * In this case, this class outputs an `<esi:include>` directive that
+ * loads the misc/track_ai_bot.php script. This technique will only work
+ * for CDNs that support ESI.
+ *
+ * The misc/track_ai_bot.php script uses this class without all of WordPress loaded.
+ * It can also be loaded outside of WordPress. Because of this, it is important
+ * that the script and this class use as few total dependencies as possible. Otherwise,
+ * AI bot tracking reduce the performance of requests to cached content.

Additionally, WP-Matomo supports WordPress networks and manages multiple sites and their tracking codes.
 
 To use this plugin the Matomo web analytics application is required. If you do not already have a Matomo setup (e.g., provided by your web hosting service), you have two simple options: use either a [self-hosted Matomo](http://matomo.org/) or a [cloud-hosted Matomo by InnoCraft](https://www.innocraft.cloud/?pk_campaign=WP-Piwik).
 
 **Requirements:** PHP 7.0 (or higher), WordPress 5.0 (or higher), Matomo 4.0 (or higher)
- 
+
 **Languages:** English, Albanian, Chinese, Dutch, French, German, Greek, Hungarian, Italian, Polish, Portuguese (Brazil). Partially supported: Azerbaijani, Belarusian, Hindi, Lithuanian, Luxembourgish, Norwegian, Persian, Romanian, Russian, Spanish, Swedish, Turkish, Ukrainian
