+# Apprise can send a notification to almost all of the most popular 
+# notification services available to us today such as: 
+# Telegram, Discord, Slack, Amazon SNS, Gotify, etc.
+# It can be used as an evolution of Hook Notification, which will be
+# dismissed in the future, eventually.
+# Set APPRISE to 1 to enable, 0 to disable.
+# Set APPRISE_URL according to the service you want to invoke.
+# Set APPRISE_ATTACH to get the report attached to the notification if a 
+# warning is issued. Not all services support this option.
+# Change APPRISE_BIN only if needed.
+# Apprise documentation and URL examples can be found here: 
+# https://github.com/caronc/apprise
+# You can use multiple Apprise URLS separated by spaces.
+# Example with Discord and Telegram:
+# APPRISE_URL="discord://<your-webook-url> tgram://<your-bot-token-here>/<your-chat-id-here>"
