 What is Alabaster?
 ==================
 
 Alabaster is a visually (c)lean, responsive, configurable theme for the `Sphinx
-<http://sphinx-doc.org>`_ documentation system.
+<https://www.sphinx-doc.org>`_ documentation system.
 It requires Python 3.9 or newer and Sphinx 3.4 or newer.
 
 It began as a third-party theme, and is still maintained separately, but as of
 Sphinx 1.3, Alabaster is an install-time dependency of Sphinx and is selected
 as the default theme.
 
 Live examples of this theme can be seen on `this project's own website
-<https://alabaster.readthedocs.io/>`_, `paramiko.org <http://paramiko.org>`_,
