 Simply do 'include passenger' and it will be installed. 
 
+Configuration
+-------------
+
 If you need to install a specific version of passenger or
 librack-ruby, you can specify the version to be installed by providing
 a variable, for example:
 
 $passenger_ensure_version = "2.2.3-2~bpo50+1"
 $librack-ruby_ensure_version = "1.0.0-2~bpo50+1"
+
+If you need to set different munin plugin configuration values, you
+can also do so as follows:
+
+$passenger_memory_munin_config = "user root\nenv.passenger_memory_stats /opt/bin/passenger-memory-stats"
+$passenger_stats_munin_config = "user root\nenv.PASSENGER_TMPDIR=/var/tmp\n"
