 ## Overview
 
 Installs and configures Logstash.
+
+## Quick Start
+
+```puppet
+  class { 'logstash::web':
+    frontend            => 'kibana',
+    discover_nodes      => ['es1.example.com:9200', 'es2.example.com:9200'],
+    proxy_elasticsearch => true,
+  }
+```
+
+## Usage Considerations
+
+You will want to add security with certs and firewalls when using this
+module.
+
+This module is recently split out of the monolithic OpenStack Infra system-config
+repo.  It is gaining flexibility but for now may be more opinionated than
+what you really want.
+
+Example to bring up logstash web interface or kibana
+
+Example usage:
+
+```puppet
+  class { 'logstash::web':
+    frontend            => 'kibana',
+    discover_nodes      => ['es1.example.com:9200', 'es2.example.com:9200'],
+    proxy_elasticsearch => true,
+  }
+```
+
+Example to install a logstash indexer
+
+Example usage:
+
+```puppet
+
+  class { 'logstash::indexer':
+    conf_template => 'my_org_module/indexer.conf.erb',
+  }
+```
+
+Where index.conf.erb looks like:

+is a sub project under the OpenStack umbrella, and so has more process
+associated with it than your typical Puppet module.
+
+This module is under the direction of the openstack-infra team.
