+### Placeholders/Variables ###
+
+The following set of variables is exposed to the ejs template (404 page example):
+
+```js
+{
+  title: 'Resource not found',
+  message: 'The requested resource could not be found but may be available again in the future.',
+  code: '404',
+  language: 'en',

+  footer: 'Tech Contact <a href="mailto:info@example.org">info@example.org</a>',
+  myvar: 'Hello World'
+}
+```
+
+To generate dynamic titles/content based on the current variable set, each variable is exposed as `placeholder` (surrounded by `%`). 
+
+You can also define custom variable within the page definitions, everything is merged togehter.
+
 ### Modify the HTML template ###
 
 The HTML template is based on [ejs](https://github.com/mde/ejs) and located in [assets/template.ejs](assets/template.ejs) - you can apply any kind of changes.
