+Templates
+---------
+
+With the help of the ``adafruit_templateengine`` library, it is possible to achieve somewhat of a
+server-side rendering of HTML pages.
+
+Instead of using string formatting, you can use templates, which can include more complex logic like loops and conditionals.
+This makes it very easy to create dynamic pages, witout using JavaScript and exposing any API endpoints.
+
+Templates also allow splitting the code into multiple files, that can be reused in different places.
+You can find more information about the template syntax in the
+`adafruit_templateengine documentation <https://docs.circuitpython.org/projects/templateengine/en/latest/>`_.
