If the repository for your {% data variables.product.prodname_pages %} site contains submodules, their contents will automatically be pulled in when your site is built.

You can only use submodules that point to public repositories, because the {% data variables.product.prodname_pages %} server cannot access private repositories.

Use the `https://` read-only URL for your submodules, including nested submodules. You can make this change in your _.gitmodules_ file.
