Multiline strings with no indent

Question

How do you have a multiline string with no leading spaces and still be properly aligned with method? Here are some of my attempts. The one that is working is not very fun...

module Something
  def welcome
"
Hello

This is an example.  I have to write this multiline string outside the welcome method
indentation in order for it to be properly formatted on screen. :(
"
  end
end

module Something
  def welcome
    "
    Hello

    This is an example.  I am inside welcome method indentation but for some reason
    I am not working...
    ".ljust(12)
  end
end

module Something
  def welcome
    "Hello\n\n"+
    "This is an example.  I am inside welcome method indentation and properly"+
    "formatted but isn't there a better way?"
  end
end

UPDATE

Here's a method from the ruby style guide:

code = <<-END.gsub(/^\s+\|/, '')
  |def test
  |  some_method
  |  other_method
  |end
END
# => "def test\n  some_method\n  other_method\nend\n"

As of Ruby 2.3.0, there is a built in method for this: [<<~]

indented = 
<<-EOS
  Hello

  This is an example. I have to write this multiline string outside the welcome method indentation in order for it to be properly formatted on screen. :(
EOS

unindented =
<<~EOS
  Hello

  This is an example. I have to write this multiline string outside the welcome method indentation in order for it to be properly formatted on screen. :(
EOS

puts indented #=>

  Hello

  This is an example. I have to write this multiline string outside the welcome method indentation in order for it to be properly formatted on screen. :(

puts unindented #=>

Hello

This is an example. I have to write this multiline string outside the welcome method indentation in order for it to be properly formatted on screen. :(
