I know you have some documentation in the theme instruction on how to make the gallery, but I’m confused by the last instruction: “Now choose this page as menu.” What does that mean?
I have uploaded four images that I want to put on one gallery and I have made a page that has the four-column gallery layout, but now what do I do? Sorry, I feel bad for asking when it is on the instruction but I just can’t figure it out!
Now choose this page as menu means you go to the dashboard-> appearance-> menus and add the gallery menu. So that it will be display on your navigation.
Just create a gallery from custom post type (Galleries) and create a gallery from there. You may use different category for different gallery. Then it will work as in our demo site.
