Collaboration means file storage, document management, video conferencing, shared event calendars, and things like that. As a rule, people tend to trust personal life and business to third-party services. However, there is an option to keep it all on your own server.
We choose [Nextcloud](https://nextcloud.com/) - free software for convenient scheduling and file storage.
To follow the steps below, you'll need to connect to the server via SSH with administrative rights. A basic understanding of the command line is beneficial ;)
