+# Nagios Mattermost Plugin
+A plugin for Nagios to enable notifications to Mattermost Open Source Chat.
+
+# Usage
+Assuming you are using Nagios 4, the steps are:
+
+1. Copy _mattermost.py_ to /usr/local/nagios/libexec.
+2. Create the notification command:
+        define command {
+              command_name notify-service-by-mattermost
+              command_line /usr/local/nagios/libexec/mattermost.py --url [URL] --hostalias "$HOSTNAME$" --notificationtype "$NOTIFICATIONTYPE$" --servicedesc "$SERVICEDESC$" --servicestate "$SERVICESTATE$" --serviceoutput "$SERVICEOUTPUT$"
+        }
+
+        define command {
+              command_name notify-host-by-mattermost
+              command_line /usr/local/nagios/libexec/mattermost.py --url [URL] --hostalias "$HOSTNAME$" --notificationtype "$NOTIFICATIONTYPE$" --hoststate "$HOSTSTATE$" --hostoutput "$HOSTOUTPUT$"
+        }
+3. Create the contact:
+        define contact {
+          contact_name                             mattermost
+          alias                                    Mattermost
+          service_notification_period              24x7
+          host_notification_period                 24x7
+          service_notification_options             w,u,c,r
+          host_notification_options                d,r
+          service_notification_commands            notify-service-by-mattermost
+          host_notification_commands               notify-host-by-mattermost
+        }
+
+4. Add the contact to a contact group:
+        define contactgroup{
+            contactgroup_name   network-admins
+            alias               Network Administrators
+            members             email, mattermost
+        }
