\section{The Octopus code}  Octopus was started in 2002 in the group of professor Angel Rubio at the University of the Basque Country UPV/EHU  in San Sebastian, Spain (or Donostia, as the city is called in the native Basque language). The main feature of Octopus is real-time TDDFT propagation, a method that have been recently proposed at the time for the calculation of excited states properties. This method has now been implemented in several electronic structure packages \cite{Schleife_2012,Schleife_2014,Walter_2008,Meng_2008,Ren_2010} and used for different types of calculations \cite{Alonso_2008,Andrade_2009}.
