+General configuration
+=====================
+Review the [defaults](defaults/main.yml) for a full set of configurable parameters. Here are the most interesting ones:
+
+`bind9_backup_config: [true, false]`: Backup each named.conf.* file or not. Default is 'true'. This setting is useful for testing out configuration changes but can clutter up the destination directory quite a bit if used across many updates.
+
+`bind9_debug_config: [true, false]`: Print the resulting YAML configuration tree that was sent to the configuration template. Default is 'false'. Useful for comparing with the resulting named.conf files and comparing values.
+
+`bind9_config_indent: [integer]`: Indentation level for the configuration template. Default is '4'. Set this value to suit your style. Tabs are not supported.

+named.conf
+==========
 bind configuration is set through the various bind9_*_config parameters. These are, in order of precedence:
 1. bind9_default_config
 2. bind9_group_config
