-Developed by [Daniel Hansson](https://github.com/enoch85) and the Nextcloud community. Nextcloud GmbH does not offer support for the VM in the [maain branch](https://github.com/nextcloud/vm/tree/main) (full-version), as we only support manual tarball/zip-package installations. You can download the official Nextcloud VM appliance ([also from this repo](https://github.com/nextcloud/vm/tree/official-basic-vm)) from [our website](https://download.nextcloud.com/vm/Official-Nextcloud-VM.zip) to get a stripped down version for testing if you rather want to skip all the manual steps in our documentation.
