• Every page says what nspawn does, without comparing it with the tools it matches; names of real things (Docker Hub, Dockerfile, the Docker API nspawn serves) stay.
• building.md: ADD of local archives (what replaces what, parents, owners, modes, times, FIFOs, devices, extended attributes) and of URLs (Last-Modified), SOURCE_DATE_EPOCH, the context's times and file capabilities, a context tar on standard input keeping its owners, a RUN's hostname buildkitsandbox and tmpfs mode 1777, a step a signal ends exiting 128 plus the signal, the # check= directive, --provenance=false and --sbom=false, the variables systemd-nspawn adds and USER root:GROUP.
• compose.md: anonymous volumes (MACHINE_anon_HEX, up -V, down -v, rm -v), a network made anew when its definition changes, down SERVICE with -p NAME and no -f taking the services that depend on it, and bind sources compose cannot look into.
• machines.md: an app's empty NOTIFY_SOCKET, the forms logs --since and --until take, and --tail.
• networking.md and faq.md: the forward exception goes in ahead of time where docker or ufw is installed.
• reference.md: logs and events --since and --until, logs --tail, images alone, and --sbom and --provenance refused unless they ask for none.
• hugo.yaml: documented version 2.2.0.

The behaviours were checked with the 2.2.0 packages on the Fedora 44, Ubuntu 24.04 and Arch test VMs (the end-to-end suite and targeted runs), and the site builds and renders with docker compose up.
