Setting a Markdown processor for your GitHub Pages site using Jekyll
You can choose a Markdown processor to determine how Markdown is rendered on your GitHub Pages site.
Who can use this feature?
GitHub Pages is available in public repositories with GitHub Free and GitHub Free for organizations, and in public and private repositories with GitHub Pro, GitHub Team, GitHub Enterprise Cloud, and GitHub Enterprise Server.
Note
While the github-pages gem remains supported for some workflows, GitHub Actions is now the recommended approach for deploying and automating GitHub Pages sites.
People with write permissions for a repository can set the Markdown processor for a GitHub Pages site.
You can use GitHub Flavored Markdown with either processor.
On GitHub, navigate to your site's repository.
In your repository, browse to the _config.yml file.
In the upper right corner of the file view, click to open the file editor.

Find the line that starts with markdown: and change the value to kramdown or GFM. The full line should read markdown: kramdown or markdown: GFM.
Click Commit changes...
In the "Commit message" field, type a short, meaningful commit message that describes the change you made to the file. You can attribute the commit to more than one author in the commit message. For more information, see Creating a commit with multiple authors.
Below the commit message fields, decide whether to add your commit to the current branch or to a new branch. If your current branch is the default branch, you should choose to create a new branch for your commit and then create a pull request. For more information, see Creating a pull request.
