+## Messaging team when the GitHub action completes (extra credit)
+
+We chose Discord as our message system. 
+
+First, we created a new text-channel (labeled **#github-actions**) and set up a Webhook.

+
+With the Webhook URL ready, we added it to our case study 1 repository.
+(here, we use a different method than the in-class demo)
+
+We navigated to the "**Settings**" tab in GitHub case study 1 repo, then went to "**Webhooks**" section on the left. We clicked the "**Add webhook**" button in the upper right corner.

+
+To ensure proper message formatting, we appended “**/github**” to the end of the URL. We set the content type as “**application/json**” and configured it to send us all notifications.

+
+After testing, we found that it worked seamlessly, and we all enjoyed the convenience it provided!
