+=========================================
+Process data with operators and workflows
+=========================================
+
+An operator is the main object used to create, transform, and stream data in DPF.
+
+They can perform different modifications of the data: direct mathematical operations,
+averaging on the mesh, changes in the model locations.... They can also be chained together
+to create workflows for more complex operations and customizable results.
+
+The tutorials in this section present how to create and use these operators and workflows in PyDPF-Core.
+
+For more information on how to program with PyDPF-Core check the
+:ref:`ref_tutorials_language_and_usage` tutorial.
