It should be the same as before. If this is the first time you use, follow these steps.
Open iTunes and plug in your iPhone. On the left sidebar there should be your iPhone name (If you can't find the sidebar, go to iTunes menu bar, under View, select Show Sidebar), go to your iTunes playlist and drag the songs you want to your iPhone. For all of the songs, go to your iPhone music library, even if you don't have songs, and on the bottom there should be a blue-ish bar. There might be a box saying "Autofill from iTunes library" click that ONLY if you want All songs from your iTunes to your iPhone.
