 # Newtype
 
-Rust has strong static types. This can be very different than what you are used to if you are coming from a loosely-typed language. Don't worry, though. Once you get used to them, you'll find the types actually make your life easier. Why? Because you are making implicit assumptions explicit.
+What if in some cases we want a type to behave similar to another type or 
+enforce some behaviour at compile time where using only type aliases would 
+not be enough? 
 
-A really convenient application of the Rust type system is the Newtype pattern.
+For example, if we want to create a custom `Display` implementation for `String` 
+due to security considerations (e.g. passwords).
+
+For such cases we could use the `Newtype` pattern to provide __type safety__ and __encapsulation__.
