 ### `avro` codec
 
-The `avro` codec writes an event as an [Apache Avro](https://avro.apache.org/) document. Because Avro requires a schema, you may either define the schema or have Data Prepper automatically generate it. Defining your own schema is recommended, as this will allow it to be tailored to your particular use case.
+The `avro` codec writes an event as an [Apache Avro](https://avro.apache.org/) document. Because Avro requires a schema, you may either define the schema or have Data Prepper automatically generate it. Defining your own schema is recommended because this will allow it to be tailored to your particular use case.
 
 When you provide your own Avro schema, that schema defines the final structure of your data. Any extra values inside any incoming events that are not mapped in the Arvo schema will not be included in the final destination. Data Prepper does not allow the use of the `include_keys` or `exclude_keys` with a custom schema. This is to avoid confusion between a custom Arvo schema and the `include_keys` or `exclude_keys` sink configurations.
