The document discusses how to organize a nationwide Linux Presentation Day (LPD) event in Germany to promote open source software. It describes how the 2015 event was organized with a central headquarters coordinating local Linux user groups (LUGs) and open source organizations. The local groups handled logistics, promotion, and content tailored to their area. The campaign focused on mainstream and technology media. Despite challenges coordinating between groups, the initial LPD was more successful than expected, inspiring plans for another in 2016 and possibilities to expand the event across Europe.
