+platform configuration and make sure it is also supported by the target
+Nextcloud branch.

+Do not copy a PHP version from this manual into automation. The repository

+Nextcloud versions move forward.

+Node.js and npm

+Use the Node.js and npm versions declared in LibreSign's current
+``package.json`` ``engines`` section.

+Do not hard-code the versions from this manual in development tooling. The
+application manifest is the source of truth.

 .. note::
    If you encounter problems with these setups, please open an issue in the corresponding repository.
 
-After running the Docker setup, check if Nextcloud is available at ``http://localhost``.  
-If it is not, run ``docker ps`` and look for the ``nextcloud`` container (or ``ghcr.io/juliushaertl/nextcloud-dev-php**``).  
-If you cannot find it, the setup likely failed; please repeat the previous step.
+When using `LibreCodeCoop/nextcloud-docker-development
+<https://github.com/LibreCodeCoop/nextcloud-docker-development/>`__, follow
+that repository's current quick-start and hostname documentation. Its shared
+development proxy exposes each Compose project through its own
+``*.localhost`` HTTPS hostname instead of requiring a fixed application
+port.
+
+If the environment does not become ready, use its documented diagnostics and
+``docker compose ps``/logs rather than assuming a fixed container name or
+URL.
 
 Once Nextcloud is running, go to the setup folder and locate ``volumes/nextcloud/apps-extra``.  
 Clone the LibreSign repository into this folder .
