-(such as `float`, `str`, `bytes`, `datetime`, ...), or other dataclasses.
+(such as `float`, `str`, `bytes`, `datetime`, ...), `Union`, or other dataclasses.
+
+### Union (de)serialization coercion 
+
+Typically the Union type; `Union[X, Y]` means—from a set theory perspective—either `X` or `Y`, i.e., an unordered set, howevever the order of the sub-types defines the precedence when attempting to ether deserialize or serialize the value per [here](https://github.com/lovasoa/marshmallow_dataclass/blob/master/marshmallow_dataclass/union_field.py). 
+
+For example, 
+
+```python
+from typing import Union
+
+from dataclasses import dataclass
+
+
+@dataclass
+class Person:
+    name: str
+    age: Union[int, float]
+
+
+PersonSchema = marshmallow_dataclass.class_schema(Person)
+PersonSchema().load({"name": "jane", "age": 50.0})
+# => Person(name="jane", age=50)
+```
+
+will first (sucessfully) try to coerce `50.0` to an `int`. If coercion is not desired the `Any` type can be used with the caveat that values will not be type checked without additional [validation](https://marshmallow.readthedocs.io/en/stable/marshmallow.validate.html).

typing-extensions constraint causes CI failures on dependant projects
marshmallow_dataclass 8.5.3 depends on `typing-extensions (>=3.7.2,<3.8.0)`
https://github.com/lovasoa/marshmallow_dataclass/blob/fa6c28980ccfe45742cdc9430bfb3b737690935f/setup.py#L32

but black 21.9b0 depends on `typing-extensions>=3.10.0.0`
https://github.com/psf/black/blob/79575f3376f043186d8b8c4885ef51c6b3c36246/setup.py#L82

Are there any plans to relax constraints on typing-extensions?
