    How do I install these formulae?
    --------------------------------
    Just `brew tap homebrew/#{name}` and then `brew install <formula>`.
    If the formula conflicts with one from Homebrew/homebrew or another tap, you can `brew install homebrew/#{name}/<formula>`.
    You can also install via URL:
    ```
    brew install https://raw.githubusercontent.com/Homebrew/homebrew-#{name}/master/<formula>.rb
    ```
    Docs
    ----
    `brew help`, `man brew`, or the Homebrew [docs][].
    [docs]:https://github.com/Homebrew/homebrew/blob/master/share/doc/homebrew/README.md#readme
    EOS
    puts template if ARGV.verbose?
    path = Pathname.new('./README.md')
    raise "#{path} already exists" if path.exist?
    path.write template
  end
end
