  The energy output of massive stars plays an important role in the evolution of star-forming galaxies. The observational signatures of superbubbles are commonly 100 pc to kpc sized structures in the interstellar medium: the interior sometimes emits X-rays, the absence of colder gas in the same place has motivated the term HI holes, whereas 'supershells' refers to HI and emission line features in the cavity walls. Superbubbles are important structuring elements in star-forming galaxies and are the main source of hot gas. They sweep up denser gas, which may trigger further star formation. When they open up into the gaseous halo of galaxies, they mediate the exchange of mass, metals, Cosmic rays and magnetic fields with the halo and beyond. When superbubbles combine they may trigger substantial galactic outflows. Despite the importance of superbubbles in the context of galactic-scale feedback, basic questions are still unanswered: where does the injected energy go? Which conditions lead to galactic winds, which ones to galactic fountains? How is the dynamics in different gas phases linked to the energy input and the star formation? What is the role of Cosmic rays and magnetic fields? How can we predict mass and energy outflow rates? In order to answer such questions, it is necessary to combine multi-wavelength data with theoretical work. The aim of this workshop is to bring together experts in the respective areas to review recent progress and promote synergies across the field. This is now particularly timely, because hot gas velocities in the Milky Way have just recently been measured via radioactive decay lines with the INTEGRAL satellite, because of other new data from e.g. the ALMA, Effelsberg, eVLA, FERMI and Herschel telescopes, and also because of advances in the theoretical realm, not only due to the steady increase of computer power, but also via progress regarding code development, e.g. the inclusion on non-equilibrium ionisation into hydrodynamic simulations. Last but not least, it is now time to prepare for eROSITA, which is expected to produce a new soft X-ray all-sky survey where superbubbles in nearby galaxies will feature prominently.
