    #{summary}
    #{pastel.bold.underline('DESCRIPTION')}
      Displays the list of gems that would be updated by `bundle update`, allowing you
      to navigate them by keyboard and pick which ones to update. A changelog URL,
      when available, is displayed alongside each update. Gems with known security
      vulnerabilities are also highlighted.
      Your Gemfile.lock will be updated conservatively based on the gems you select.
      Transitive dependencies are not affected.
      More information: #{pastel.blue('https://github.com/mattbrictson/bundle_update_interactive')}
    #{pastel.bold.underline('EXAMPLES')}
      Show all gems that can be updated.
      #{pastel.green('bundle update-interactive')}
      The "ui" command alias can also be used.
      #{pastel.green('bundle ui')}
      Show updates for development and test gems only, leaving production gems untouched.
      #{pastel.green('bundle update-interactive')} #{pastel.yellow('-D')}
      Allow the latest gem versions, ignoring Gemfile pins. May modify the Gemfile.
