Template example does not work

As in title. Crashes with:

...
  File "/usr/lib/python3.4/site-packages/jinja2/_compat.py", line 36, in reraise
    raise value.with_traceback(tb)
  File "./md_cell_list.tpl", line 1, in <module>
    {%- extends 'html_basic.tpl' -%}
jinja2.exceptions.TemplateNotFound: html_basic.tpl

I have a funny feeling all these examples are outdated, actually...
