+## Deprecation
+
+The current `nixos-container`-implementation should be considered deprecated as soon as the new
+implementation is part of a stable NixOS release. To give end-users a reasonable time to migrate,
+it should be kept and maintained for **at least two release cycles**, if necessary even longer.
