Are secondary nav links in 5.7?

UPDATE

Ok, I have created a 2nd level menu in my primary menu. But the secondary terms are not being written to the list in my sidebar in the Garland theme. Will this only work in a theme enabled with some secondary template tag?

The "add item" interface suggests, with great confusion, that I can simply add my secondary level to the primary menu, and level 2, and have both primary and secondary use the same menu. But again, it';s not showing the secondary level.

But this this doc suggests I use another menu. I simply don't understand how I then parent the terms. Is there a clearly instruction for how to creatre a simple, 2 level menu without all this ambiguity?

UPDATE 2
This is the documentation for d5. It discusses editing the primary menu, and adding a random menu. Nothing about secondary menus. What I am missing?

This is some pretty maddening stuff. I created a secondary menu . Now i have no idea how set my blocks as defaults around a common center content (so that if I create a node like "About" in the path from my primary, the existing front page blocks appear on that node too).

I no longer wonder why some many thousands of users say that Drupal is not for them. It's not that the power isn't here. It's just that there doesn't seem to be too much documentation geared to rank newbies. It's either cookbooks with too much detail, or documentation without enough. With Joomla, someone can be making sites in 2 hours. I have been working with drupal for 5 days, and am still pretty much completely mired in conceptual dramas, and no closer to a working site. The worst part is, i really love it. I just wish i could use it.
