- A Stage (previously called Stage 3) is a minimal set of Gentoo binaries to build a system in any way possible.
- Containers and Images provide a ready-to-use Gentoo system, e.g. for cloud or virtual machine usage.
- All release files are signed with an official OpenPGP key and distributed via world-wide download mirrors.
