-Installs Java 7u51 and unlimited key length security policy files..
+Installs Java 7 and unlimited key length security policy files..
 
 
 ## Usage
 
 ```puppet
+# Install the default version of both the JDK and JRE
 include java
 ```
 
+## Parameters
+
+You can customise this module by configuring some optional class parameters. Usually you'd do this via Hiera, but you could also explicitly pass those parameters in puppet code like `class { 'java': $update_version => '42', }`.
+
+* `update_version`: The 'update' part of the JRE/JDK version to install. For example, if you specify `51`, the module would install java 7u51
+* `base_download_url`: A base path from which the JRE and JDK packages should be downloaded. For example, if you specify `https://myorg.example/dist/java`, this module would download the jre from `https://myorg.example/dist/java/jre-7u51-macosx-x64.dmg`.
+
+All of these parameters have sensible defaults, and are provided if you need more control.
+
+Example hiera data in YAML:
+
+```yaml
+java::update_version: '51'
+java::base_download_url: 'https://myorg.example/dist/java'
+```
