These templates allow you to create a new section with a pre-set layout and blocks. This is speeding up our process of creating new brand guidelines sites, and we hope you find it useful. Down the track, we'll add support for you to save your own templates, letting you easily build pages, one templated section at a time.
We're also working to bring real-time previews for these templates, allowing you to see what your new section will look like styled in your friend's colors and typography styles.
