 An object called `info` of type [`PackagerSettings`](https://github.com/fvarrui/JavaPackager/blob/master/src/main/java/io/github/fvarrui/javapackager/packagers/PackagerSettings.java) is passed to all templates with all plugin properties.
 
+You can use [default templates](https://github.com/fvarrui/JavaPackager/tree/master/src/main/resources) as examples to create your own templates, and use the `extra` map property to add your own properties in the plugin settings to use in your custom templates (e.g. `${info.extra["myProperty"]}`).

 ### Additional JVM options at runtime
 
 When you build your app, all configuration details are hardcoded into the executable and cannot be changed without recreating it or hacking with a resource editor. JavaPackager introduces a feature that allows to pass additional JVM options at runtime from an `.l4j.ini` file (like [Launch4j](http://launch4j.sourceforge.net/docs.html) does, but available for all platforms in the same way). So, you can specify these options in the packager's configuration (packaging time), in INI file (runtime) or in both.
