Add new categories on the navbar

[ItaloP23]

Hello and thanks for the theme. I am trying to set it up with my content (I really like the style). I wanted to know if it's possible to add content in this way:

In config.toml I add new menu in the navbar:

[[menu.main]] name = "Blog" url = "/Blog" weight = 2

and I've created a new folder in Content/Blog but when I put a new markdown file (created from command line in hugo hugo new Blog/somefile.md ) it doesn't show when I go from the navbar in the Blog section.

Can the theme work also with this content organization or it has been made only for content written in the Content/post directory?

I am sorry if some question will be silly but I am totally new and I am trying to learn (I have attended some youtube course on Hugo so I am not totally new but I still have lot to learn).

Thanks
