+A data object is basically a Map wrapper. A DataContainer is an object which contains a Data object, there are multiple containers such as Instance, ItemStack, Entity, Block (in a particular way, the data object is specified when setting a block).
+
+Basically, it is used to link values to an element of the game.
+
+For instance:
+
+```java
+Data data = dataContainer.getData();
+data.set("test", 1, Integer.class);
+int test = data.get("test");
+```
+
+## Serializable data
+A SerialiableData object can, as the name imply, be serialized.
+
+It should be used in hand with our [Storage system](https://github.com/Minestom/Minestom/wiki/Storage)
