+It is recommended to run this command through a cron-job, ideally in combination with the `media:removeunused`
+command. It's important to run the `removeunused`-command *after* the tagging command, because otherwise removed
+images will not be untagged in the Pixxio media library.
 
 Note: At this point, the auto-tagging feature is not really optimized for performance. The command merely
 iterates over all assets which were imported from Pixxio and checks if tags need to be updated.
