-Unlike method-set properties or overrides, to set fields inside areas (*primaryFields*, *secondaryFields*, *auxiliaryFields*, *headerFields*, *backFields*), this library make available a dedicated array-like interface, with just the essential methods: `push()` and `pop()`.
+Unlike method-set properties or overrides, to set fields inside areas (*primaryFields*, *secondaryFields*, *auxiliaryFields*, *headerFields*, *backFields*), this library make available a dedicated interface that extends native Array, to let you perform all the operations you need on the fields. Still, **shouldOverride** option, will determine whether default inserted fields should be kept or not.
