title: Rails wicked_pdf, convert page as pdf
body: <p>I have a normal Rails layout which is my normal Site.</p>
  
  <p>I want a Button on this page to convert/transform this page into 
  a PDF file.</p>
  
  <p>I want to do it with this gem:
  <a href="https://github.com/mileszs/wicked_pdf" rel="nofollow">https://github.com/mileszs/wicked_pdf</a></p>
  
  <p>I added <code>gem 'wicked_pdf'</code> to my Gemfile, but now how can I convert the actual page? </p>
