 ## Explicit my.cnf templating
 
 In some situation it is preferable to explicitly define the attributes needed in a `my.cnf` file. This is enabled by adding categories to the `node[:percona][:conf]` attributes. All keys found in the `node[:percona][:conf]` map will represent categories in the `my.cnf` file. Each category contains a map of attributes that will be written to the `my.cnf` file for that category. See the example for more details.
