 # Note
 
-- Accessing a property that doesn't exist will create an empty `Config()`.
-- Clean up stranded empty `Config`s with `delete_empty!(::Config)`.
-
-```julia
-c = Config()
-
-c.one.two.three.four.five.six == Config()
-
-# Internally we make the assumption that empty Config's shouldn't be there.
-# Some functions will therefore call `delete_empty!` under the hood:
-isempty(c) == true
-```
+- Accessing a non-existent property creates an `Undefined`.  
+- This is necessary for assigning deeply nested properties (an eventual `setindex!` after nested `getindex`-es).
+  - `config.a == Undefined(config, [:a])`, `config.a.b == Undefined(config, [:a, :b])`, etc.
+  - `config.a.b.c = 1` == `Undefined(config, [:a, :b])[:c] = 1`
