+### Password requirements ###
+
+Beginning with the 3.0.0 release, default passwords are no longer provided by this module. This was a insecure default as every instances of observium setup with these defaults would use the same passwords. 
+
+With the removal of the default, users now need to specify these password when using this module. There are two methods to do this in Puppet.
+
+1. Via parameters through resource like declarations. (Least preferred as you cannot protect these values)
+```
+class { 'observium':
+  db_password       => 'your_password_here',
+  rootdb_password   => 'your_password_here',
+  snmpv3_authpass   => 'your_password_here',
+  snmpv3_cryptopass => 'your_password_here',
+  admin_password    => 'very_secure',
+}
+```
+
+2. Via environment hiera. (Preferred as we can encrypt these values)
+Within environment hiera place the values as shown.
+```
+---
+observium::db_password: "your_password_here"
+observium::rootdb_password: "your_password_here"
+observium::snmpv3_authpass: "your_password_here"
+observium::snmpv3_cryptopass: "your_password_here"
+observium::admin_password: "very_secure"
+```
+
+These values should be encrypted using the [hiera-eyaml][11] gem. See Puppet [documentation][12].
 
 ### Beginning with observium
 
 In its most basic form you can install observium by
 ```
-include observium
+class { 'observium':
+  db_password       => 'your_password_here',
+  rootdb_password   => 'your_password_here',
+  snmpv3_authpass   => 'your_password_here',
+  snmpv3_cryptopass => 'your_password_here',
+  admin_password    => 'very_secure',
+}
 ```
