How to make category page links work

[Charada]

Hi -

 

Thanks again for all your help in previous posts!

 

I've went ahead and changed the categories and all the names to fit my needs.

 

Now, I'm having trouble figuring out how to make the page links work.

 

When I click on the new categories I've made, it says this page cannot be found.

 

Which I understand because I haven't created them yet, and don't know where to.

 

Where do I go to create those pages, and also how to edit the content in those pages.

 

Thanks!
