This Synthesis Report is meant to collect and put together the results of the six different Country Reports (for Greece, Germany, Italy, UK, Ireland and Sweden) developed by the partners of the FOSS4SMEs project. Each Country Report, as the main deliverable foreseen by the IO1/A1 ‘Research’ phase, comprises an overarching and comprehensive overview about the different national situations with relation to the usage of Free and Open Source Software (FOSS) within SMEs across Europe.
