+###### Perform calculations {#perform_calculations}
+
+##### Basic Electronic Structure calculations {#basic_electronic_structure_calculations}
+
+In this section, basic and very common functionalities of the KKR code
+are described. Each topic is explained in terms of a prototype example.
+After following them one by one, you should be well prepared to perform
+your first own calculations.
