Possibly @command{goredo} package already exists for your distribution:
@itemize
@item ALT Linux @url{http://www.sisyphus.ru/ru/srpm/Sisyphus/goredo, Sisyphus}
@item Arch Linux @url{https://aur.archlinux.org/packages/goredo/, AUR}
@item @url{https://www.freshports.org/devel/goredo/, FreeBSD ports}
@item macOS @url{https://formulae.brew.sh/formula/goredo, Homebrew}
@end itemize

Preferable way is to download tarball with the signature from website:

@example
$ [fetch|wget] http://www.goredo.cypherpunks.ru/download/goredo-@value{VERSION}.tar.zst
$ [fetch|wget] http://www.goredo.cypherpunks.ru/download/goredo-@value{VERSION}.tar.zst.sig
$ gpg --verify goredo-@value{VERSION}.tar.zst.sig goredo-@value{VERSION}.tar.zst
$ zstd -d < goredo-@value{VERSION}.tar.zst | tar xf -
$ cd goredo-@value{VERSION}/src
$ go build -mod=vendor
$ ./goredo -symlinks        # create redo-* commands symlinks
$ export PATH=`pwd`:$PATH   # let your system know about goredo
@end example

@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.

For the very first time it is necessary to get signing public key and
import it. It is provided below, but you should check alternative
resources.

It is also @command{go get}-able:

@example
$ go get go.cypherpunks.ru/goredo
$ goredo -symlinks
@end example

If you have problems with @code{*.golang.org}'s inability to verify
authenticity of @code{go.cypherpunks.ru} TLS connection, then you can
disable their usage by setting @env{$GOPRIVATE=go.cypherpunks.ru}. You
can override CA certificate file path with @env{$SSL_CERT_FILE} and
@env{$GIT_SSL_CAINFO} environment variables.

You can obtain development source code with
@command{git clone git://git.cypherpunks.ru/goredo.git}
(also you can use @url{https://git.cypherpunks.ru/goredo.git}).
