 The Avro schema can be specified by name and loaded using the schema store:
 
 ```ruby
 class MyModel
-  include Avromatic::Model.build(schema_name :my_model)

 ```ruby
 class MyModel
-  include Avromatic::Model.build(schema_name :my_model, mutable: true)
+  include Avromatic::Model.build(schema_name: :my_model, mutable: true)
 end
 ```
 
 Generated models include attributes for each field in the Avro schema
 including any default values defined in the schema.
