I set up a local Drupal 8 multisite, using Acquia dev desktop. Its working fine. I added all Drupal 8 core files to my local repository and pushed them to a central remote repository.

• in sites/default/settings.php I added $config_directories['staging'] = 'sites/default/config/staging';to make the configuration directory versionable.
• All sites (main site, subside1 and subside2) has different databases

But what about the sites/subside1/ and sites/subside2/ config files? Do I have to add also a different path for those files? Do those has to be versioned or not?

I want to clone my repo to make instances of this multisite for staging and live environments.
