Modifying a page is even simpler than creating one. As with [creating a page](/contributing/adding-a-page/), you can create a new branch in your forked repository. Open the document you want to change in your favorite editor, make your updates, preview the site locally, and [submit a pull request](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/creating-a-pull-request).

When editing an existing page, keep the original topic and audience in mind. If your change moves a page into a different folder, update any links that point to it and check the relevant `index.yml` files.

Retype uses Markdown to format and style text, among other things. If you want more information about Markdown syntax, we recommend the [Retype formatting guide](https://retype.com/guides/formatting/) and [Daring Fireball's Markdown basics](https://daringfireball.net/projects/markdown/basics).
