 Sometimes for tests you don't want to calculate actual functions
 and you want to pass another functions instead.
 
-To do so, you can add "dependency_overrides" key to the aplication.
-It's a dict that is passed as additional context to dependency resolvers.
+To do so, you can add "dependency_overrides" or "values_overrides" to the aplication's state.
+These values should be dicts.

 ```python
-    my_app["dependency_overrides"] = {original_dep: 2}
+    my_app["values_overrides"] = {original_dep: 2}
 ```

+But `values_overrides` only overrides values. If you want to
+override functions, you have to use `dependency_overrides`. Here's an example:

+```python
+def replacing_function() -> int:

+my_app["dependency_overrides"] = {original_dep: replacing_function}
+```
+
+The cool point about `dependency_overrides`, is that it recalculates graph and
+you can use dependencies in function that replaces the original.
