 ## Example usage
 
 ### Standalone
 
 ```puppet
 include ::redis
 ```
 
 ### Master node
 
 ```puppet
 class { '::redis':
   bind => '10.0.1.1',
 }
 ```
 
 With authentication
 
 ```puppet
 class { '::redis':
   bind       => '10.0.1.1',
   masterauth => 'secret',
 }
 ```
 
 ### Slave node
 
 ```puppet
 class { '::redis':
   bind    => '10.0.1.2',
   slaveof => '10.0.1.1 6379',
 }
 ```
 
 With authentication
 
 ```puppet
 class { '::redis':
   bind       => '10.0.1.2',
   slaveof    => '10.0.1.1 6379',
   masterauth => 'secret',
 }
 ```
 
 ### Redis 3.0 Clustering
 
 ```puppet
 class { '::redis':
   bind                 => '10.0.1.2',
   appendonly           => true,
   cluster_enabled      => true,
   cluster_config_file  => 'nodes.conf',
   cluster_node_timeout => 5000,
 }
 ```
 
 ### Multiple instances
 
 
 ```puppet
 $listening_ports = [6379,6380,6381,6382]
 
 class { '::redis':
   default_install => false,
   service_enable  => false,
   service_ensure  => 'stopped',
 }
 
 $listening_ports.each |$port| {
   $port_string = sprintf('%d',$port)
   redis::instance { $port_string:
     service_enable => true,
     service_ensure => 'running',
     port           => $port,
     bind           => $facts['networking']['ip'],
     dbfilename     => "${port}-dump.rdb",
     appendfilename => "${port}-appendonly.aof",
     appendfsync    => 'always',
     require        => Class['Redis'],
   }
 }
 ```
 
 ### Manage repositories
 
 Disabled by default but if you really want the module to manage the required
 repositories you can use this snippet:
 
 ```puppet
 class { '::redis':
   manage_repo => true,
 }
 ```
 
 On Ubuntu, "chris-lea/redis-server" ppa repo will be added. You can change it by using ppa_repo parameter:
 
 ```puppet
 class { '::redis':
   manage_repo => true,
   ppa_repo    => 'ppa:rwky/redis',
 }
 ```
 
 **Warning** note that it requires [puppetlabs/apt](https://forge.puppet.com/puppetlabs/apt) on Ubuntu distros. On Red Hat [puppet/epel](https://forge.puppet.com/puppet/epel) is needed unless the installation is using Software Collections. In that case will install `centos-release-scl-rh` from CentOS extras. For RHEL or other RHEL-derivatives this isn't managed.
 
 ### Redis Sentinel
 
 Optionally install and configuration a redis-sentinel server.
 
 With default settings:
 
 ```puppet
 include ::redis::sentinel
 ```
 
 With adjustments:
 
 ```puppet
 class { '::redis::sentinel':
   master_name      => 'cow',
   redis_host       => '192.168.1.5',
   failover_timeout => 30000,
 }
 ```
 
 ### Soft dependency
 
 When managing the repo, it either needs [puppetlabs/apt](https://forge.puppet.com/puppetlabs/apt) or [puppet/epel](https://forge.puppet.com/puppet/epel).
 
+For administration of sysctl it depends on [herculesteam/augeasproviders_sysctl](https://forge.puppet.com/herculesteam/augeasproviders_sysctl).
+
 ## `redis::get()` function
 
 This function is used to get data from redis.
 You must have the 'redis' gem installed on your puppet master.
 
 Functions are documented in [REFERENCE.md](REFERENCE.md)

 # @summary Allows various administrative settings for Redis
