title: Shiny layout - how to add footer disclaimer?
body: <p>How can I add footer notes or disclaimer in Shiny's UI? This is my current layout,</p>
  
  <pre><code>shinyUI(
    pageWithSidebar(
  
      headerPanel("My Title"),
  
      sidebarPanel("sidebar"),
  
      mainPanel("hello world")
  )
  )
  </code></pre>
  
  <p>I have checked this <a href="http://shiny.rstudio.com/articles/layout-guide.html" rel="noreferrer">page</a> but no mention of this. Any ideas?</p>
  
  <p>What I need is,</p>
  
  <pre><code>My Title
  
  sidebar   hello world (plots)
  
  ----------------------------
  
        disclaimer
  </code></pre>
