The first step for using Yammi is to get your songs into Yammi's database by having your harddisk scanned. For this to work correctly, you should first check your configuration (Configuration->Settings) and make sure that the directory "base directory for scanning" is pointing to the base directory of your song collection. Also, give a path for "trash directory for deleted song files", as this directory is needed when you want to delete songs within Yammi (Yammi does not delete any files, but moves them to this directory and skips this directory when scanning for new songs). Now start your database update (Database->Update), which should insert all found songs into Yammi's database. After the update you are ready to use Yammi, for example search for songs, categorize them or enqueue them to your media player. For more information about scanning your harddisk, or for information about scanning CDs, see "Updating Database" in "Advanced Topics".
