You can put any file type into your `/content` directories, but Hugo uses the `markup` front matter value if set or the file extension (see `Markup identifiers` in the table below) to determine if the markup needs to be processed, e.g.:

* Markdown converted to HTML
* [Shortcodes](/content-management/shortcodes/) processed
* Layout applied

## List of content formats

The current list of content formats in Hugo:

| Name  | Markup identifiers | Comment | 
| ------------- | ------------- |-------------|
| Goldmark  | md, markdown, goldmark  |Note that you can set the default handler of `md` and `markdown` to something else, see [Configure Markup](/getting-started/configuration-markup/).{{< new-in "0.60.0" >}} |
| Blackfriday | blackfriday  |Blackfriday will eventually be deprecated.|
|MMark|mmark|Mmark is deprecated and will be removed in a future release.|
|Emacs Org-Mode|org|See [go-org](https://github.com/niklasfasching/go-org).|
|Asciidoc|asciidoc, adoc, ad|Needs Asciidoc or [Asciidoctor][ascii] installed.|
|RST|rst|Needs [RST](http://docutils.sourceforge.net/rst.html) installed.|
|Pandoc|pandoc, pdc|Needs [Pandoc](https://www.pandoc.org/) installed.|
|HTML|html, htm|To be treated as a content file, with layout, shortcodes etc., it must have front matter. If not, it will be copied as-is.|

The `markup identifier` is fetched from either the `markup` variable in front matter or from the file extension. For markup-related configuration, see [Configure Markup](/getting-started/configuration-markup/).


## External Helpers

Some of the formats in the table above needs external helpers installed on your PC. For example, for Asciidoc files, Hugo will try to call the `asciidoctor` or `asciidoc` command. This means that you will have to install the associated tool on your machine to be able to use these formats. ([See the Asciidoctor docs for installation instructions](https://asciidoctor.org/docs/install-toolchain/)).

Hugo passes reasonable default arguments to these external helpers by default:

- `asciidoc`: `--no-header-footer --safe -`
- `asciidoctor`: `--no-header-footer --safe --trace -`
- `rst2html`: `--leave-comments --initial-header-level=2`
- `pandoc`: `--mathjax`

{{% warning "Performance of External Helpers" %}}
Because additional formats are external commands generation performance will rely heavily on the performance of the external tool you are using. As this feature is still in its infancy, feedback is welcome.
