+ * @section eolian_main_compiling How to compile
+ *
+ * Eolian is a library your application links to. The procedure for this is
+ * very simple. You simply have to compile your application with the
+ * appropriate compiler flags that the @c pkg-config script outputs. For
+ * example:
+ *
+ * Compiling C or C++ files into object files:
+ *
+ * @verbatim
+   gcc -c -o main.o main.c `pkg-config --cflags eolian`
+   @endverbatim
+ *
+ * Linking object files into a binary executable:
+ *
+ * @verbatim
+   gcc -o my_application main.o `pkg-config --libs eolian`
+   @endverbatim
+ *
+ * See @ref pkgconfig
+ *
+ * @section eolian_main_next_steps Next Steps
+ *
+ * After you understood what Eolian is and installed it in your system
+ * you should proceed understanding the programming interface.
