 # implicitdict
+
+This library primarily provides the `ImplicitDict` base class which enables the inheriting class to implicitly be treated like a `dict` with entries corresponding to the fields of the inheriting class.  Simple example:
+
+```python
+class MyData(ImplicitDict):
+    foo: str
+    bar: int = 0
+    baz: Optional[float]
+
+data: MyData = ImplicitDict.parse({'foo': 'asdf', 'bar': 1}, MyData)
+assert json.dumps(data) == '{"foo": "asdf", "bar": 1}'
+```
+
+See [class documentation for `ImplicitDict`](src/implicitdict/__init__.py) and [test_normal_usage.py](tests/test_normal_usage.py) for more information.
