The Admin Interface
-------------------

You've finished the installation process, congratulations. If you fire up the
server, you can now visit the admin page on http://localhost:8000/admin

As you can see, the admin panel is very empty. This is because no bundle has
provided admin functionality for the admin bundle yet. Fortunately, you'll
learn how to do this in the :doc:`next chapter <creating_an_admin>`.

.. _`installation chapter`: https://getcomposer.org/doc/00-intro.md

In the old RST parser, the last paragraph is correctly rendered as something apart from the previous figure:

However, in the new parser, the last paragraph is wrongly considered the "figcaption" of the figure:
