 MongoDB databases. Our practical experience is that setting the `max_nesting_level` to 2 or 3
 produces the clearest and human-readable schemas.
 
+:::tip
+The `max_table_nesting` parameter at the source level doesn't automatically apply to individual 
+resources when accessed directly (e.g., using `source.resources["resource_1"])`. To make sure it 
+works, either use `source.with_resources("resource_1")` or set the parameter directly on the resource.

+You can directly configure the `max_table_nesting` parameter on the resource level as:
+
+```py
+@dlt.resource(max_table_nesting=0)
+def my_resource():
+    ...
+```
+or
+```py
+my_source = source()
+my_source.my_resource.max_table_nesting = 0

 ### Modify schema
 
 The schema is available via `schema` property of the source.
