title: Rails App without DB: Easiest way to provide a small editable text (displayed as news on homepage)
body: <p>I have a very small Rails app for a client that serves nearly only static content. It has no database in the background.</p>
  
  <p>My client now needs a way to provide a small text which is shown on the home page. In it he wants to state the current deliver deadline of his product (which varies a lot). The easiest thing would be a small page where he could change the text in a textarea, protected by a password.</p>
  
  <p>I wonder whether there is a very easy way for offering something like that without attaching a full DB to the app?</p>
