+nerdctl (the containerd CLI) plus the rootless containerd + buildkit + CNI
+stack, as ONE candy. Composed by a box that wants the opt-in `engine: nerdctl`
+engine.
+
+## What it installs
+
+- **Native packages** on Arch/CachyOS/Omarchy and Alpine: `nerdctl`,
+  `cni-plugins`, `rootlesskit`, `slirp4netns`, `buildkit`, `fuse-overlayfs`,
+  `crun`, `iptables-nft` (arch) / `iptables` (alpine).
+- **Non-native distros** (Fedora/Debian/Ubuntu) install the pinned,
+  sha256-verified `nerdctl-full` tarball (step `nerdctl-full-tarball`), which
+  supplies nerdctl + containerd + `containerd-fuse-overlayfs-grpc` + CNI +
+  buildkit + rootlesskit in one archive.
+- `/etc/nerdctl/nerdctl.toml` (charly namespace + CNI path) and
+  the `charly` CNI network conflist at `/etc/cni/net.d/charly.conflist`.
+- The **nested-pod posture**: userns-scoped `cap_add: ALL`, `/dev/fuse`,
+  `/dev/net/tun`, `unmask=/proc/*`.
+
+## Engine capability
+
+The `engine: nerdctl` word is served by `opencharly/plugin-nerdctl`
+(out-of-process) or compiled in; every engine op delegates to
+`container.InvokeEngineOp("nerdctl", …)` in the spec module. nerdctl has no
+`--keep-id`, so the start-plan runs the workload as `--user 0:0` (uid 0 == the
+host user under rootless), guaranteeing uid-identical sharing; a non-zero uid
+needs the subuid caveat.
+
+## Use when
+
+Working with the nerdctl engine, the layer-nerdctl candy, or an
+`engine: nerdctl` deploy.
