 This simple three stage flow provides a simple, predictable content processing flow for the user, and removes several other development concerns:
 
 1. As the templating language of choice, Nunjucks is always processed first, allowing its templating capabilities to be used to the full extent.
-Its syntax is also the most compatible and independent of the other stages.
+   Its syntax is also the most compatible and independent of the other stages.
 
 2. Secondly, Markdown is **rendered before HTML**, which produces more HTML. This also allows core Markdown features (e.g. code blocks) and Markdown plugins with eccentric syntaxes to be used without having to patch the HTML parser.
 
 3. Having processed possibly conflicting Nunjucks and Markdown syntax, HTML is then processed last.
 
 ### Demonstrating the content processing flow
+
 To demonstrate the content processing flow, let's take a look at a small toy MarkBind file:
+
 ```markdown
 {% raw %}{% set myVariable = "Item" %}
 
 # A basic level 1 header
+
 There will be 5 items here:
+
 <ul>
 {% for item in [1, 2, 3, 4] %}
    <li>{{ myVariable }} #{{ item }}</li>

 At the first step of the processing flow, the `VariableProcessor` converts Nunjucks template code into HTML:

 Notice that `myVariable` is consumed and that the unordered list is expanded.
 
 Next, the NodeProcessor converts Markdown to HTML:

 It does this by traversing the node graph and matching node titles to their HTML equivalents. This includes custom components as well (e.g. `<panel .. />`).
 `include` nodes are recursively traversed and converted.
