# contrib The `contrib` directory contains packages that do not belong in the core containerd packages but still contribute to overall containerd usability. Package such as Apparmor or Selinux are placed in `contrib` because they are platform dependent and often require higher level tools and profiles to work. Packaging and other built tools can be added to `contrib` to aid in packaging containerd for various distributions. ## Testing Code in the `contrib` directory may or may not have been tested in the normal test pipeline for core components.
