 /**
- * WordPress Cron Implementation for hosts, which do not offer CRON or for which
- * the user has not set up a CRON job pointing to this file.
+ * A pseudo-CRON daemon for scheduling WordPress tasks
+ *
+ * WP Cron is triggered when the site receives a visit. In the scenario
+ * where a site may not receive enough visits to execute scheduled tasks
+ * in a timely manner, this file can be called directly or via a server
+ * CRON daemon for X number of times.
+ *
+ * Defining DISABLE_WP_CRON as true and calling this file directly are
+ * mutually exclusive and the latter does not rely on the former to work.
  *
  * The HTTP request to this file will not slow down the visitor who happens to
  * visit when the cron job is needed to run.
