 MyBatis Dynamic SQL provides a specialized rendering strategy for queries used with the MyBatis Spring `ItemReader` implementations. Queries should be rendered as follows:
 
 ```java
-        SelectStatementProvider selectStatement =  SelectDSL.select(person.allColumns())
-                .from(person)
-                .where(lastName, isEqualTo("flintstone"))
-                .build()
-                .render(SpringBatchUtility.SPRING_BATCH_READER_RENDERING_STRATEGY);
+  SelectStatementProvider selectStatement =  SelectDSL.select(person.allColumns())
+      .from(person)
+      .where(lastName, isEqualTo("flintstone"))
+      .build()
+      .render(SpringBatchUtility.SPRING_BATCH_READER_RENDERING_STRATEGY); // render for Spring Batch
 ```
 
 ### Creating the Parameter Map
 
 The `SpringBatchUtility` provides a method to create the parameter values Map needed by the MyBatis Spring `ItemReader`. It can be used as follows:
 
 ```java
-        MyBatisCursorItemReader<Person> reader = new MyBatisCursorItemReader<>();
-        reader.setQueryId(PersonMapper.class.getName() + ".selectMany");
-        reader.setSqlSessionFactory(sqlSessionFactory);
-        reader.setParameterValues(SpringBatchUtility.toParameterValues(selectStatement));
+  MyBatisCursorItemReader<Person> reader = new MyBatisCursorItemReader<>();
+  reader.setQueryId(PersonMapper.class.getName() + ".selectMany");
+  reader.setSqlSessionFactory(sqlSessionFactory);
+  reader.setParameterValues(SpringBatchUtility.toParameterValues(selectStatement)); // create parameter map
 ```
