To publish you can just create pages or posts.
Once created you link them to a menu, through Appearance on the left tool bar. That is how I published this page.
I simply created it, selected the sidebars on the right hand side and then Published or Updated it.
Then I went to the menu item, found the page on the left and added it. It appeared at the bottom of all the menu items. I then dragged it under Editors (a menu only you editors and I can see). Do not forget to save the menu at this point.
Now pages can be quite complicated. You can write code which gives rise to a link (short code) for that code which you put in a page and publish, just like above. Once on a menu and selected your code will execute.
I am here to help, I appreciate your help, believe me.
