+# Hiera Puppet
+
+## Description
+This module configures [Hiera](https://github.com/puppetlabs/hiera) for Puppet.
+
+## Usage
+This class will write out a hiera.yaml file in either /etc/puppetlabs/puppet/hiera.yaml or /etc/puppet/hiera.yaml (depending on if the node is running Puppet Enterprise or not).
+
+```puppet
+class { 'hiera':
+  hierarchy => [
+    '%{environment}/%{calling_class}',
+    '%{environment}',
+    'common',
+  ],
+}
+```
+
+The resulting output in /etc/puppet/hiera.yaml:
+```yaml
+---
+:backends: - yaml
+:logger: console
+:hierarchy:
+  - "%{environment}/%{calling_class}"
+  - "%{environment}"
+  - common
+
+:yaml:
+   :datadir: /etc/puppet/hieradata
+```
