# The `stack unpack` command
~~~text
stack unpack PACKAGE [--to ARG]
~~~
`stack unpack` downloads a tarball for the specified package and unpacks it.
By default:
* the download is for the most recent version of the package in the package
index (eg Hackage). Specify the package name and its version (for example,
`acme-missiles-0.1.0.0`) for a particular version of the package; and
* the package is unpacked into a directory named after the package and its
version. Pass the option `--to ` to specify the destination
directory.
