+#### Decimal Logical Types
+
+The decimal logical type, for bytes and fixed types, is currently the only logical type that requires additional
+attributes. For decimals, precision must be specified and scale may optionally be specified. `avro-builder`
+supports both of these attributes for bytes and fixed decimals. See the Avro
+[spec](https://avro.apache.org/docs/current/spec.html#Decimal) for more details.
 
 ### Abstract Types
 
 Types can be declared as abstract in the DSL. Declaring a type as abstract
 prevents the rake task from generating an Avro JSON schema for the type.
