People with write permissions for a repository can set the Markdown processor for a {% data variables.product.prodname_pages %} site.

{% data variables.product.prodname_pages %} supports two Markdown processors: [kramdown](http://kramdown.gettalong.org/) and {% data variables.product.prodname_dotcom %}'s own extended [CommonMark](https://commonmark.org/) processor, which is used to render {% data variables.product.prodname_dotcom %} Flavored Markdown throughout {% data variables.product.product_name %}. For more information, see "[About writing and formatting on {% data variables.product.prodname_dotcom %}](/articles/about-writing-and-formatting-on-github)."

You can use {% data variables.product.prodname_dotcom %} Flavored Markdown with either processor, but only our CommonMark processor will always match the results you see on {% data variables.product.product_name %}.

{% data reusables.pages.navigate-site-repo %}
2. In your repository, browse to the *_config.yml* file.
{% data reusables.repositories.edit-file %}
4. Find the line that starts with `markdown:` and change the value to `kramdown` or `GFM`.
