-You can configure this extension to disable parts of it, or to enable some feature flags

-To do so you need to call set_configuration function after the import:
-
-```python
-import alembic_postgresql_enum
-
-alembic_postgresql_enum.set_configuration(
-    alembic_postgresql_enum.Config(
-        add_type_ignore=True,
-    )
-)
-```
-
-Default configuration:
-```python
-alembic_postgresql_enum.Config(
-    add_type_ignore = False,
-    include_name = lambda _: True,
-    drop_unused_enums = True,
-    detect_enum_values_changes = True,

+To do so you need to call set_configuration function after the import:

+
+Available options:
+
+- `add_type_ignore` (`False` by default) - flag that can be turned on 
+to add `# type: ignore[attr-defined]` at the end of generated `op.sync_enum_values` calls.
+This is helpful if you are using type checker such as `mypy`.
+`type: ignore` is needed because there is no way to add new function to an existing alembic's `op`.
+
+- `include_name` (`lambda _: True` bby default) - it adds ability to ignore process enum by name in similar way alembic allows to define `include_name` function. 
+This property accepts function that takes enum name and returns whether it should be processed.  
+
+- `drop_unused_enums` (`True` by default) - feature flag that can be turned off to disable clean up of undeclared enums
+
+- `detect_enum_values_changes` (`True` by default) - feature flag that can be turned off to disable generation of `op.sync_enum_values`.
