 By getting involved with Phonon, you can choose between three different main tasks.
 * '''Using the Phonon API''', which allows you to develop your own multimedia application. '''This is discussed here.'''
 * '''Hacking the Phonon library'''.
 * '''Writing Phonon backend''', this consists in writing interfaces that allows Phonon to use different sound/video engine. This usually requires good skills and knowledge of the engine you interface with.
