Development
The basis for Rocketship, what we call 'the Skeleton', is a composer.json file + a specific folder-structure and files.
Development starts in this private repo: https://gitlab.com/hostingplatform/skeletons-skeleton8
The content is essentially the same as in our public repo: https://www.drupal.org/project/dropsolid_rocketship
Except that some Dropsolid-specific things are filtered out before pushing to said repo using a Gitlab Pipeline.
