+# `core`
+
+Bootstraps the foundational CLI tools required by the rest of the dotfiles setup.
+
+## Installs
+
+| CLI    | macOS | Debian |
+| ------ | ----- | ------ |
+| `curl` | —     | `apt`  |
+| `git`  | —     | `apt`  |
+| `make` | —     | `apt`  |
+| `sudo` | —     | `apt`  |
+| `wget` | —     | `apt`  |
+
+## Configures
+
+Nothing — this package only installs system packages.
+
+## Notes
+
+- On macOS, `macos-core` is a meta-target with no script of its own; it simply chains `macos-brew`, `macos-stow`, and `macos-zsh`.
+- On Debian/Ubuntu, `ubuntu-core` depends on `ubuntu-stow` and then installs packages from `core.Aptfile` via `apt-get`.
+- `make core` dispatches automatically to `macos-core` or `ubuntu-core` based on the current OS.
