 That can be handy for example with dependency injection,
 so you can only provide one main mappr that can handle everything by delegating to other mapprs.
 
+### Type converters
+
+`MapType`s are usefull for mappings that you can use from the **outside**.
+AutoMappr mapps one object to another using constructors and fields
+and you use the `.convert()` method on it.
+
+But when you need to customize an **inner** converting of types,
+there are `TypeConverter`s that help you with that.
+Boxing, `String` to `DateTime`, and stuff like that, `TypeConverter`s are your friend.
+Note since type converters are only used internally,
+you cannot in any way use them using the `.convert()` method.
+
+Global type converters are also "absorbed" from included modules.
+To make the priority crystal clear:
+
+1. (local) type converters from `MapType`, in order
+1. (global) type converters from `AutoMappr`, in order
+1. (global included) type converters from `included` modules, in order
+
+Use `MapType` for most of the things.
+Use `TypeConverter` only for cases that cannot be solve otherwise.
+
+Imagine you have an `UserDto` with a date in a `String` and a `User` model with a date in `DateTime`.
+`MapType` will handle mapping of all the constructor parameters and other fields,
+while `TypeConverter` will convert `String` to `DateTime`.
+
+```dart
+@AutoMappr(
+  [
+    MapType<UserDto, User>(
+      // MapType specific
+      converters: [
+        TypeConverter<String, DateTime>()
+      ],
+    ),
+  ],
+  converters: [
+    // or globally here
+  ],
+)
+class Mappr extends $Mappr {
+  static DateTime stringToDateTime(String source) {
+    // ...
+  }
+}
+```
+
+You can also create methods that can convert "any" (to "any") using `Object`.
+But if you work with type parameters (generics)
+note that you have to either return the correct type with correct type parameters
+or initialize it inside correctly.
+It cannot be cast successfully otherwise.
+Therefore if you need a method that converts `"any"` to `Value("any")`,
+and to make it work for `int` and `String`,
+it must look like one of these:
+
+```dart
+static Value<T> objectToValueObject<T extends Object>(T source) {
+  return Value<T>(source);
+}
+
+static Value<Object> objectToValueObject2(Object source) {
+  if (source is int) {
+    return Value<int>(source);
+  }
+
+  if (source is String) {
+    return Value<String>(source);
+  }
+
+  return Value(source);
+}
+```
+
 ### Reverse mapping
 
 When you want to create a bidirectional mapping (e.g. normal: source to target and reversed: target to source),
