Thanks for installing the Fedora package of hellanzb. To configure the client for use, copy /usr/share/doc/hellanzb/hellanzb.conf.sample to $HOME/.hellanzb.conf and edit it appropriately. To start hellanzb, just run 'hellanzb -D'. To enqueue nzbs, drop them in the queue directory as configured in your $HOME/.hellanzb.conf. If you want Hellanzb to automatically unrar downloaded files, install the 'unrar' from a repository that provides packages Fedora can't.
