Newbie to Debian 12.7

[Gregory Forster]

Hi

    I have an older 14" HP Probook 440 with Intel core I3-4000M, 1TB 
HDD, 12GB RAM. After several weeks of debating and switching back and 
forth between Debian and Fedora, I settled upon Debian 12.7 with the 
Cinnamon desktop, for several reasons. However, there is one question I 
have regarding Debian. How do I get another repository for more apps? 
Or, how do  I get certain apps, such as: Bible Time, KeePass, VLC Media 
Player, Audacity?
