 Creating filters is very easy. Basically they are just methods which take one parameter and return a modified string. You can use your own filters by passing an array of modules to the render call like this @template.render(assigns, [MyTextFilters, MyDateFilters])
 
+<pre><code>
 module TextFilter
   def textilize(input)
     RedCloth.new(input).to_html
   end
 end
+</code></pre>
 
+<pre><code>
 @template = Liquid::Template.parse(" {{ '*hi*' | textilize }} ")
-@template.render({}, [TextFilter])              # => "<b>hi</b>" 
+@template.render({}, :filters => [TextFilter])              # => "<b>hi</b>" 
+</code></pre>

 Alternatively you can also register your filters globally

 module TextFilter

 h3. Create your own tag blocks
 
 All tag blocks are parsed by liquid. To create a new block you just have to inherit from Liquid::Block and register your block with Liquid::Template
 
+<pre><code>
   class Random < Liquid::Block
