 # Notes
 
+## Nested objects
+
 If you use nested objects, like MyClass1Object.MyClass2Object.Var1, please use the approach "[Attribute Mapping](https://docs.automapper.org/en/latest/Attribute-mapping.html)". Otherwise you will get a "missing maps" error.
+You can also use Mapper.CustomMappings (see example above).
+
+### Multiple projects
 
 If the attributed classes are not within your default project assembly, please set Mapper.Assembly manually.
