 ## Usage
 
 1. Setup configuration for anonymizing target tables/columns to `masking.yml`
 
+    *NOTE: the columns which doesn't mention here will be NOT anonymized, it stays as it is.*
+
     ```yaml
-      # table_name:
-      #   column_name: masked_value
+    # table_name:
+    #   column_name: masked_value
 
-      users:
-        string: anonymized string
-        email: anonymized+%{n}@example.com # %{n} will be replaced with sequential number
-        integer: 12345
-        float: 123.45
-        boolean: true
-        null_column: null
-        date: 2018-08-24

-        # When a column name is suffixed with `?`, the original NULL value will not be anonymized.

     A value will be implicitly converted to a compatible type. If you prefer to explicitly convert, you could use a tag as defined in [YAML Version 1.1](http://yaml.org/spec/current.html#id2503753)
 
     ```yaml
-      not-date: !!str 2002-04-28
+    not-date: !!str 2002-04-28
     ```
 
     String should be matched with [MySQL String Type]( https://dev.mysql.com/doc/refman/8.0/en/string-type-overview.html). Integer/Float should be matched with [MySQL Numeric Type](https://dev.mysql.com/doc/refman/8.0/en/numeric-type-overview.html). Date/Time should be matched with [MySQL Date and Time Type](https://dev.mysql.com/doc/refman/8.0/en/date-and-time-type-overview.html).
 
     *NOTE: MasKING doesn't check actual schema's type from the dump. If you put incompatible value it will cause an error during restoring to the database.*
