Preferable way is to download tarball with the signature from
website and, for example, run tests with benchmarks:

@example
$ [fetch|wget] http://www.gocheese.cypherpunks.ru/gocheese-@value{VERSION}.tar.zst
$ [fetch|wget] http://www.gocheese.cypherpunks.ru/gocheese-@value{VERSION}.tar.zst.sig
$ gpg --verify gocheese-@value{VERSION}.tar.zst.sig gocheese-@value{VERSION}.tar.zst
$ zstd -d < gocheese-@value{VERSION}.tar.zst | tar xf -
$ cd gocheese-@value{VERSION}
$ redo test all # or go build -mod=vendor
@end example

It uses @url{http://cr.yp.to/redo.html, redo} build system for that
examples. You can use either dozen of various implementations, or at
least minimalistic POSIX shell @command{contrib/do} (just replace
@command{redo} with @command{contrib/do} in the example above) included
in tarball.

@include download.texi

You @strong{have to} verify downloaded tarballs integrity and
authenticity to be sure that you retrieved trusted and untampered
software. @url{https://www.gnupg.org/, GNU Privacy Guard} is used
for that purpose.
