{% ifversion pages-custom-workflow %}If you are publishing from a branch, changes{% else %}Changes{% endif %} to your site are published automatically when the changes are merged into your site's publishing source. {% ifversion pages-custom-workflow %}If you are publishing from a custom {% data variables.product.prodname_actions %} workflow, changes are published whenever your workflow is triggered (typically by a push to the default branch). {% endif %}If you want to preview your changes first, you can make the changes locally instead of on {% data variables.product.product_name %}. Then, test your site locally. For more information, see "Testing your {% data variables.product.prodname_pages %} site locally with Jekyll."
