+### Systemd Custom Config
+To add additional variables to the systemd EnvironmentFile by hiera:
+```puppet
+wildfly::custom_config:
+  - "LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/sap/jco/sap_jco_3.0.16_64:/opt/oracle/instantclient_11_2/lib"
+  - "NLS_LANG=GERMAN_GERMANY.WE8ISO8859P15"
+  - "LANG=de_DE@euro"
+```
+
 ## Limitations
 
 Some of this module public defined types  (`widfly::datasources`, `wildfly::messaging`, `wildfly::undertow`, etc) were built for Wildfly 8.x and may not work with other versions. When there is a proven alternative for a different version, examples might be provided, otherwise you'll need to build your own abstraction using `wildfly_resource` or `wildfly::resource`.
