+LXC vs LXD vs Proxmox Containers vs Docker::
+
+LXC is a userspace interface for the Linux kernel containment
+features. Through a powerful API and simple tools, it lets Linux users
+easily create and manage system containers. LXC, as well as the former
+OpenVZ, aims at *system virtualization*, i.e. allows you to run a
+complete OS inside a container, where you log in as ssh, add users,
+run apache, etc...
++
+LXD is building on top of LXC to provide a new, better user
+experience. Under the hood, LXD uses LXC through 'liblxc' and its Go
+binding to create and manage the containers. It's basically an
+alternative to LXC's tools and distribution template system with the
+added features that come from being controllable over the network.
++
+Proxmox Containers also aims at *system virtualization*, and thus uses
+LXC as the basis of its own container offer. The Proxmox Container
+Toolkit is called 'pct', and is tightly coupled with {pve}. That means
+that it is aware of the cluster setup, and it can use the same network
+and storage resources as fully virtualized VMs. You can even use the
+{pve} firewall, create and restore backups, or manage containers using
+the HA framework. Everything can be controlled over the network using
+the {pve} API.
++
+Docker aims at running a *single* application running in a contained
+environment. Hence you're managing a docker instance from the host with the
+docker toolkit. It is not recommended to run docker directly on your
+{pve} host.
++
+NOTE: You can however perfectly install and use docker inside a Proxmox Qemu
+VM, and thus getting the benefit of software containerization with the very
+strong isolation that VMs provide.
