See [fosslinux.com](https://www.fosslinux.com/49956/install-debian-11-minimal-server.htm)

Summary:
1. Download the ‘netinst’ version of Debian 11 from the official website. From [here at debian.org](https://www.debian.org/CD/netinst/#netinst-stable).
2. Create storage medium if needed (can install directly from `.iso` if in a VM).
3. Install.
    1. This will install the base system.
    2. You want to select:
      1. standard system utilities (you can use e.g. [busybox](/linux/system-software/Busybox).
      2. Web Server (if needed -- perhaps you are running a [node](/lang/js/node) server so
          don't need [apache2](/linux/net/server/httpd/apache2).
      3. SSH server. This is a must if you want to administer the VM remotely.
    4. You can then login.
    5. I would then install tmux, vim, rsync, wget, curl.

## Virtualisation
See [here for giving a VM its own IP address](/linux/virtual/net/Give-VM-own-IP-Address).
