+# This is a shell script for using the Pushover (https://pushover.net) push service.
+# Copy this script to the netdata plugin folder which by default is "/usr/libexec/netdata/plugins.d/".
+# In the config file for the alarm you want to use it for add:
+# "exec: /usr/libexec/netdata/plugins.d/alarm-pushover.sh"
+# Once Pushover client is installed on your phone or computer, you need to create an account to receive a
+# user token. This is needed so the push reaches your device.
+#
+# Generate an apptoken at https://pushover.net and insert that and the usertoken into the
+# "healt_pushover_tokens.conf" file which has to reside in the netdata config dir which by
+# default is "/etc/netdata/".
+#
+# Further help for pushover: https://pushover.net/faq
