<h1>Downloads</h1>

<p>
After downloading a binary release suitable for your system,
please follow the <a href="/doc/install">installation instructions</a>.
</p>

<p>
If you are building from source,
follow the <a href="/doc/install/source">source installation instructions</a>.
</p>

<p>
See the <a href="/doc/devel/release.html">release history</a> for more
information about Go releases.
</p>

<p>
  As of Go 1.13, the go command by default downloads and authenticates
  modules using the Go module mirror and Go checksum database run by Google. See
  <a href="https://proxy.golang.org/privacy">https://proxy.golang.org/privacy</a>
  for privacy information about these services and the
  <a href="/cmd/go/">go command documentation</a>
  for configuration details including how to disable the use of these servers or use
  different ones.
