+When writing a package definition, developers typically need to download
+the package's source tarball, compute its SHA256 hash, and write that
+hash in the package definition (@pxref{Defining Packages}).  The
+@command{guix download} tool helps with this task: it downloads a file
+from the given URI, adds it to the store, and prints both its file name
+in the store and its SHA256 hash.
+
+The fact that the downloaded file is added to the store saves bandwidth:
+when the developer eventually tries to build the newly defined package
+with @command{guix build}, the source tarball will not have to be
+downloaded again because it is already in the store.  It is also a
+convenient way to temporarily stash files, which may be deleted
+eventually (@pxref{Invoking guix gc}).
+
+The @command{guix download} command supports the same URIs as used in
+package definitions.  In particular, it supports @code{mirror://} URIs.
+@code{https} URIs (HTTP over TLS) are supported @emph{provided} the
+Guile bindings for GnuTLS are available in the user's environment; when
+they are not available, an error is raised.
