 # civ-handler
 Handles webhook messages from Civ 6 and sends them to Discord. Civ VI sends three values and you can only set a single endpoint to push the turn notifications in a Play By Cloud game. This app sits between Discord and Civ and redirects the POSTed messages to different Discord Webhooks based on partially matching the game name to a webhook. It also prevents the same turn notification from triggering multiple times.
 
+Offers a log.html to view sent events and to display errors such as duplicate events.
+
 Known limitations: Any MacOS user in a game with a Webhook enabled will have his/her client crash at "end turn" without a notification being sent. Aspyr has had this bug on "known bugs" page for 1.5 years at the time of updating this readme. https://support.aspyr.com/hc/en-us/articles/216979606-Civilization-VI-Mac-Known-Issues
