 # TarantoolTuple usage
 
 You can use TarantoolTuple for creating tuple which can be sent to the Tarantool instance
-or can be returned from default "crud" functions.
+or can be returned from default [tarantool/crud](https://github.com/tarantool/crud) or box methods.
 You can create TarantoolTuple with this factory `TarantoolTupleFactory`.
 See an example below:
 
-```java
-// Create a mapper factory  
-DefaultMessagePackMapperFactory mapperFactory = DefaultMessagePackMapperFactory.getInstance();
-// Create a tuple factory
-TarantoolTupleFactory tupleFactory = new DefaultTarantoolTupleFactory(mapperFactory.defaultComplexTypesMapper());
-
-// Create a tuple from listed values: [1,2.0,'3',4]
-TarantoolTuple tarantoolTuple = tupleFactory.create(1, 2.0, "3", new BigDecimal("4"));
-
-Optional<?> object = tarantoolTuple.getObject(0);
-Optional<Integer> integer = tarantoolTuple.getObject(0, Integer.class);
-
-// Returned value will have 'double' type (it is used by default). 
-Optional<?> doubleValue = tarantoolTuple.getObject(1);
-// To get 'float' value we must explicitly define the target type.
-Optional<?> floatValue = tarantoolTuple.getObject(1, Float.class);
-
-Optional<?> stringValue = tarantoolTuple.getObject(2);
-
-Optional<?> bigDecimalValue = tarantoolTuple.getObject(3);
