+## Setup (Debian)
+
+1. Add Kubic repo (pre Debian 11∕Ubuntu 20.10 only):
+    1. Install dependencies: `apt install curl wget gnupg2`
+    1. Get OS info: `source /etc/os-release`
+    1. Add repo: `echo "deb http://download.opensuse.org/repositories/devel:/kubic:/libcontainers:/stable/xUbuntu_${VERSION_ID}/ /" | tee /etc/apt/sources.list.d/kubic-libcontainers.list`
+    1. Add GPG key (old way): `wget -nv https://download.opensuse.org/repositories/devel:kubic:libcontainers:stable/xUbuntu_${VERSION_ID}/Release.key -O- | apt-key add -`
+1. Install: `apt install podman`
+1. Verify install: `podman info`
+1. (Optional) Add Docker alias: `ln -s /usr/bin/podman /usr/bin/docker`

+
+## Usage
+
+### General
+
+- See [Docker usage](../docker/#usage).
+    - Most commands are Docker clones and simply replacing `docker` with `podman` in the command will typically work.
+    - Configuration files are a bit different.
+
+### Networking
+
+- IPv6:
+    - Doesn't seem to be as broken/neglected as in Docker.
+    - Add `--ipv6 --subnet=<subnet>/64` to enable on bridges (with NAT and firewalling, like IPv4).
