Hey Carrie,

currently the posts page handling is the same in full-site editing as it is in current themes.

If you have an index.html file with a query block that inherits the main query (something like https://gist.github.com/fklein-lu/1f0e59d79f16300c63a2308a13d6cc1b) the reading settings will be respected, and the posts page will show the block archive.

If you want to customize the blog archive template further, you can create a home.html template, and it will be selected as the current template when the blog is displayed.

Cheers,
Fränk
