* Make the backup puller a full-fledged script after all.

* Finish the main portion.

* Remove version tag to avoid log errors on Docker 26.0, Compose 2.25.0.

* Try moving to a smaller, faster, more stable image.

* Move Nextcloud to the stable tag.

* Add shortcut aliases.

* Rename container website to www.

* Do not install the latest of the PHP or Node programs if a version already exists in the container.

* We need git!!

* Try only git and the PHP interpretor.

* Remove comments.

* Install express at the image layer, not during runtime.

* Let the app install express after all.

* Remove warning about apt CLI.

* Try to cache the express download/install.
