      <li>
        Extract the archive you downloaded into /usr/local, creating a Go tree
        in /usr/local/go.
        <p>
          <strong>Important:</strong> This step will remove a previous
          installation at /usr/local/go, if any, prior to extracting.
          Please back up any data before proceeding.
        </p>
        <p>
          For example, run the following as root or through <code>sudo</code>:
        </p>
        <pre>
rm -rf /usr/local/go && tar -C /usr/local -xzf <span id="linux-filename">go1.14.3.linux-amd64.tar.gz</span>
</pre
        >
      </li>
      <li>
        Add /usr/local/go/bin to the <code>PATH</code> environment variable.
        <p>
          You can do this by adding the following line to your $HOME/.profile or
          /etc/profile (for a system-wide installation):
        </p>
        <pre>
export PATH=$PATH:/usr/local/go/bin
</pre
        >
        <p>
          <strong>Note:</strong> Changes made to a profile file may not apply
          until the next time you log into your computer. To apply the changes
          immediately, just run the shell commands directly or execute them from
          the profile using a command such as
          <code>source $HOME/.profile</code>.
        </p>
      </li>
      <li>
        Verify that you've installed Go by opening a command prompt and typing
        the following command:
        <pre>
$ go version
</pre
        >
      </li>
      <li>Confirm that the command prints the installed version of Go.</li>

    <ol>
      <li>
        Open the package file you downloaded and follow the prompts to install
        Go.
        <p>
          The package installs the Go distribution to /usr/local/go. The package
          should put the /usr/local/go/bin directory in your
          <code>PATH</code> environment variable. You may need to restart any
          open Terminal sessions for the change to take effect.
        </p>

        Verify that you've installed Go by opening a command prompt and typing

    <ol>
      <li>
        Open the MSI file you downloaded and follow the prompts to install Go.
        <p>
          By default, the installer will install Go to <code>Program Files</code>
          or <code>Program Files (x86)</code>. You can change the
          location as needed. After installing, you will need to close and
          reopen any open command prompts so that changes to the environment
          made by the installer are reflected at the command prompt.
        </p>
      </li>
      <li>
        Verify that you've installed Go.
        <ol>
          <li>
            In <strong>Windows</strong>, click the <strong>Start</strong> menu.
          </li>
          <li>
            In the menu's search box, type <code>cmd</code>, then press the
            <strong>Enter</strong> key.
          </li>
          <li>
            In the Command Prompt window that appears, type the following
            command:
            <pre>
$ go version
</pre
            >
          </li>
          <li>Confirm that the command prints the installed version of Go.</li>
