Demo page tree (Initialisation)

On a fresh / empty TYPO3 site (no pages yet), install the theme dependencies, then run:

vendor/bin/typo3 extension:setup

That imports the demo page tree from Initialisation/Demo/data.xml only when pages is empty, copies assets from Initialisation/Files/ into fileadmin/ns_theme_cleanblog, and creates config/sites/ns_theme_cleanblog/ when that site identifier does not exist yet.

Existing sites are never overwritten

If the installation already has any pages (for example 5 pages you created yourself), extension:setup will not import the demo tree and will not change your pages. A registry marker is stored so the skip stays permanent.

Safe re-runs

Running extension:setup again after a successful empty-site import does not re-import or wipe content.

Force re-import (dev only)

Only on a disposable instance:

1. Remove demo pages / reset DB if needed
2. Delete registry rows for this package, e.g. extensionDataImport keys containing ns_theme_cleanblog/Initialisation/Demo
3. Optionally remove siteConfigImport / config/sites/ns_theme_cleanblog
4. Run vendor/bin/typo3 extension:setup again on an empty page tree
