Create Main menu headings top of page

Hi I do not know & can’t find out what version Of Acme I’m using.

I am now wanting to create my main menu tabs at the top of the site.
The Headings like ‘Home” and “About” and a few more. The thing Is…

I go to pages on my dashboard and click add new,
and the page comes up where you can type in what you want to appear.
Like I typed – Home.
Then to the right It has a tab for publish.
So I click It, and It’s there when I go back
to look at the Template again.

Then another…I bring up a new – add new page; and type In
About” and Click publish. This Is suppose to put this next tab
On my template to the right Of the first one-(Home).
But It doesn’t It replaces It. Also, an option I have was to click update because That was what the publish tab turned into,

after clicking It; before I brought up the next add new page. I’m not having luck with either.

So I can not add the top main menu tabs to the top of my Acme template.
I did add some side bar menus, I don’t like how they came in yet;-but their there”

So Please tell me If you can; how to get these Tabs to hold
after typing them In? So I can add all the ones I want all at one time
and be done with It.
Thank you
Dale.
