Hugo believes that you organize your content with a purpose. The same structure that works to organize your source content is used to organize the rendered site (see [directory structure][]).
Following this pattern, Hugo uses the top level of your content organization as the content **section**.
The following example shows a content directory structure for a website that has three sections: "authors," "events," and "posts":
Hugo will automatically create pages for each section root that list all of the content in that section. See the documentation on [section templates][] for details on customizing the way these pages are rendered.
As of Hugo v0.18, section pages can also have a content file and front matter. These section content files must be placed in their corresponding section folder and named `_index.md` in order for Hugo to correctly render the front matter and content.

Hugo themes developed before v0.18 often used an `index.md`(i.e., without the leading underscore [`_`]) in a content section as a hack to emulate the behavior of `_index.md`. The hack may work...*sometimes*; however, the order of page rendering can be unpredictable in Hugo. What works now may fail to render appropriately as your site grows. It is **strongly advised** to use `_index.md` as content for your section index pages. **Note:**`_index.md`'s layout, as representative of a section, is a [list page template](/templates/section-templates/) and *not* a [single page template](/templates/single-page-templates/). If you want to alter the new default behavior for `_index.md`, configure `disableKinds` accordingly in your [site's configuration](/getting-started/configuration/).

## Content *Section* vs Content *Type*
By default, everything created within a section will use the [content type][] that matches the section name. For example, Hugo will assume that `posts/post-1.md` has a `posts` content type. If you are using an [archetype][] for your posts section, Hugo will generate front matter according to what it finds in `archetypes/posts.md`.
