 Here is some code from my website:
 
-```twig
+![A screenshot of the code that calculates the number of talks I've given.]({{site.url}}/assets/images/talk-count-code.png)
-{%- verbatim -%}
-{% set talkCount = 0 %}
 
-{% for talk in data.talks %}
+If you want, you can also [view it on GitHub](https://raw.githubusercontent.com/opdavies/oliverdavies.uk/main/source/_pages/talks.md).
-  {% for event in talk.events if 'today'|date('U') >= event.date|date('U') %}
-    {% set talkCount = talkCount + 1 %}
-  {% endfor %}
-{% endfor %}
-{%- endverbatim -%}
