Once logged into your Hygraph project, you can add a new page using the content editor.
Select the default view for Page and then add your Title, Slug, Content, and optionally pick the Chapter this page should be nested under.
Once you are happy, you can then save and publish this page to appear live on your docs site.
If this page isn't part a chapter, you can add it to the navigation by adding a new item to the Navigation entry.
You can add pages to chapters, or directly to the navigation as a nav item.
If you want to preview a page before publishing it, you can use the
Open in Preview button inside Hygraph. The starter is already configured and supports it out of the box. If you want, you can also preview it in development.
