+## What It Does
+This plugin's primary purpose is to check of the Payment Gateways we are using are still online, and to record their states as they are switched from 'testmode' to 'production'. It will send notifications to the Slack channel whenever Burning Man's 'Click and Pledge' Gatway and 'PayEezy' Gatway do the following:
+- Production -> Testmode
+- Testmode -> Production
+- Plugin Deactivated
+- Plugin Activated
+- Payment Method Enabled
+- Payment Method Disabled
+
+Because the PayEezy Gateway uses AJAX to insert WooCommerce Errors, I have included a Javascript which will record any PayEezy related errors to Google Analytics. I am intending to add functionality to allow an admin to set a specific Cart error that can trigger a Slack Notification. This would allow some general cart errors related to improper payment gateway settings to be sent to slack and improve respnse time.
