 ## packages
 
 *list* (of *string*)
 
-A list of package names to install on the image.

-- **Alpine** installs these packages with `apk`
-- **Arch Linux** installs these packages with `yay`
-- **Debian** installs these packages with `apt-get install`
-- **FreeBSD** installs these packages with `pkg`
-- **NixOS** installs these packages with `nix-env -iA`. Since it's possible to
-  specify multiple channels, you must provide the full selection path,
-  for example `nixpkgs.hello`. Note that the `nixpkgs` channel is **not**
-  added by default.

 ## repositories
 
 *dictionary* (of *string: string*)
 
-A list of extra repositories to enable with the image's package manager.
-The format is name: url, and the syntax of url varies between images.
-
-- **Alpine** uses `repo-url key-url key-name`, where `repo-url` is the URL of
-  the package repository and `key-url` is a URL from where the signing key may
-  be downloaded, and `key-name` is the name of the file written to
-  `/etc/apk/keys/`. If the name of the repo is prefixed with an @, it will use
-  that prefix in apk.
-- **Arch Linux** uses `url#key-id`, where `url` is the URL of the package
-  repository and `key-id` is the ID of the published PGP key the packages are
-  signed with.
-- **Debian** uses `url distro component key-id`, where `url` is the URL of the
-  package repository, `distro` is e.g. `jessie` or `stretch`, `component` is
-  e.g. `main` or `non-free`, and `key-id` is an optional PGP key ID to add to
-  apt-key.
-- **FreeBSD** images do not support extra package repositories.
-- **NixOS** uses `channel-url`. The repo name is relevant, since
-  `repo-name: repo-url` wil execute the commands
-  `nix-channel --add repo-url repo-name` and `nix-channel --update repo-name`.
-  Given the nature of nix, no channel is added by default.
