 This cookbook expects a `mysql` item  and a `system` item. Please refer to the official documentation on how to get this setup. It actually uses a MySQL example so it can be mostly copied. Ensure you cover the data bag items as described below.
 
+You also may set expected item names via attributes `node["percona"]["encrypted_data_bag_item_mysql"]` and `node["percona"]["encrypted_data_bag_item_system"]`.

 ### Skip passwords
 Set the `["percona"]["skip_passwords"]` attribute to skip setting up passwords. Removes the need for the encrypted data bag if using chef-solo. Is useful for setting up development and ci environments where you just want to use the root user with no password. If you are doing this you may want to set `[:percona][:server][:debian_username]` to be `"root"` also.
