+=== Mappings with direct field access
+
+MapStruct also supports mappings of `public` fields that have no getters/setters. MapStruct will
+use the fields as read/write accessor if it cannot find suitable getter/setter methods for the property.
+
+A field is considered as a read accessor if it is `public` or `public final`. If a field is `static` it is not
+considered as a read accessors.
+
+A field is considered as a write accessor only if it is `public`. If a field is `final` and/or `static` it is not
+considered as a write accessor.
