-Backend is the main calculation engine to execute circuits.
-Qibo provides backends for quantum simulation on classical hardware and quantum hardware management and control.
+:class:`qibo.backends.abstract.Backend` is the main calculation engine to execute circuits.
+Qibo provides backends for quantum simulation on classical hardware, as well as quantum hardware management and control.
 For a complete list of available backends, refer to the :ref:`Packages <packages>` section.
 To create new backends, inherit from :class:`qibo.backends.abstract.Backend` and implement
 its abstract methods. This abstract class defines the required methods for circuit execution.
