I have a new Synology DS420+ with DSM 7 and want to synchronise mainly calendars (calDAV) and contacts (cardDAV) with Nextcloud. Since Nextcloud Groupware also contains mail, I am also considering synchronising the email accounts with Nextcloud.
Is there a good (German) dummy guide for installing Nextcloud with DSM 7 on the net?
Or does the installation works like with DSM 6?
Do I need Docker / Container on the Synology for this?
