along with it that are NOT markdown.
Those assets will be copied in the same folder when building so you can just use a relative path to use them.
A summary is only defined if you put `<!-- more -->` in the content. If present in a page, the summary will be from
the start up to that tag.s
### Sections
Sections represent a group of pages, for example a `tutorials` section of your site.
Sections are only created in Gutenberg when a file named `_index.md` is found in the `content` directory.
