 ### Styles
 
 You must define absolute paths to CSS files, images, and javascripts; the best option is to use the *wisepdf_stylesheet_tag*, *wisepdf_image_tag*, and *wisepdf_javascript_tag* helpers.

 ### Page Numbering
 
 A bit of javascript can help you number your pages. Create a template or header/footer file with this:
 
-    <html>
-      <head>
-        <script>
-          function number_pages() {
-            var vars={};
-            var x=document.location.search.substring(1).split('&');
-            for(var i in x) {var z=x[i].split('=',2);vars[z[0]] = unescape(z[1]);}
-            var x=['frompage','topage','page','webpage','section','subsection','subsubsection'];
-            for(var i in x) {
-              var y = document.getElementsByClassName(x[i]);
-              for(var j=0; j<y.length; ++j) y[j].textContent = vars[x[i]];
-            }
-          }
-        </script>
-      </head>
-      <body onload="number_pages()">
-        Page <span class="page"></span> of <span class="topage"></span>
-      </body>
-    </html>
+```html
+<html>
+  <head>
+    <script>
+      function number_pages() {
+        var vars={};
+        var x=document.location.search.substring(1).split('&');
+        for(var i in x) {var z=x[i].split('=',2);vars[z[0]] = unescape(z[1]);}
+        var x=['frompage','topage','page','webpage','section','subsection','subsubsection'];
+        for(var i in x) {
+          var y = document.getElementsByClassName(x[i]);
+          for(var j=0; j<y.length; ++j) y[j].textContent = vars[x[i]];
+        }
+      }
+    </script>
+  </head>
+  <body onload="number_pages()">
+    Page <span class="page"></span> of <span class="topage"></span>
+  </body>
+</html>
+```
 
 Anything with a class listed in "var x" above will be auto-filled at render time.
 
 If you do not have explicit page breaks (and therefore do not have any "page" class), you can also use wkhtmltopdf's built in page number generation by setting one of the headers to "[page]":
 
-    render :pdf => 'filename', :header => { :right => '[page] of [topage]' }
+```ruby
+render :pdf => 'filename', :header => { :right => '[page] of [topage]' }
+```
 
 ### Configuration
 
 You can put your default configuration, applied to all pdf's at "configure_wisepdf.rb" initializer.
 
-    Wisepdf::Configuration.configure do |c|
-      c.wkhtmltopdf = '/path/to/wkhtmltopdf'
-      c.options = {
-        :layout => "layout.html",
-        :use_xserver => true,
-        :footer => {
-          :right => "#{Date.today.year}",
-          :font_size => 8,
-          :spacing => 8
-        },
-        :margin => {
-          :bottom => 15
-        }
-      }
-
-    end
+```ruby
+Wisepdf::Configuration.configure do |c|
+  c.wkhtmltopdf = '/path/to/wkhtmltopdf'
+  c.options = {
+    :layout => "layout.html",
+    :use_xserver => true,
+    :footer => {

+    },
+    :margin => {

+end

 However, the wisepdf_* helpers will use file:// paths for assets when using :show_as_html, and your browser's cross-domain safety feature will kick in, and not render them. To get around this, you can load your assets like so in your templates:
