+# `dropbox`
+
+Installs the Dropbox desktop client for cloud file sync.
+
+## Installs
+
+| App / CLI | macOS         | Ubuntu          |
+| --------- | ------------- | --------------- |
+| Dropbox   | `brew --cask` | direct download |
+| `dropbox` | —             | direct download |
+
+## Configures
+
+- No dotfiles or stow config — Dropbox manages its own state under `~/Dropbox`.
+
+## Notes
+
+- **Ubuntu**: the daemon binary lands at `~/.dropbox-dist/dropboxd`. Run it once
+  to authenticate and link your account. The `dropbox` CLI (Python script at
+  `/usr/local/bin/dropbox`) can then manage the daemon (`start`, `stop`,
+  `status`, `ls`, etc.).
+- **Ubuntu**: several Mesa/XCB libraries are installed as runtime dependencies
+  before the daemon tarball is extracted.
+- **macOS**: installed as a cask so it appears in `/Applications`; Homebrew is
+  the only prerequisite (`macos-brew`).
