Unclear Set Up Instructions

[LJ-03]

The set up instructions straight up don't work. Looks simple but it's not working and there's nothing on stack overflow that's helpful. I did as the readme asked:

add_breadcrumb "home", :root_path
  add_breadcrumb "my", :my_path

  def index
    # ...

    add_breadcrumb "index", index_path
  end

along with many other variants, but it's not working. The controller where the setup is located won't even load. I'm getting syntax errors for the colon ":" when setting it up the readme states.

SyntaxError means you have written some invalid Ruby code. Please check the code of your controller file.
