 What is Alabaster?
 ==================
 
 Alabaster is a visually (c)lean, responsive, configurable theme for the `Sphinx
-<http://sphinx-doc.org>`_ documentation system. It is Python 2+3 compatible.
+<https://www.sphinx-doc.org>`_ documentation system.
+It requires Python 3.10 or newer and Sphinx 6.2 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
-<http://alabaster.readthedocs.io>`_, `paramiko.org <http://paramiko.org>`_,
-`fabfile.org <http://fabfile.org>`_ and `pyinvoke.org <http://pyinvoke.org>`_.

 Installation
 ============
 
-The bare minimum required to install Alabaster is as follows:
+Alabaster requires **Sphinx 6.2 or newer**, and is included as the default
+theme.
 
-* If you're on **Sphinx 1.2 or older**:
+.. note::
+  If you distribute your documentation via `Read the Docs
+  <https://readthedocs.org>`_, you will need to explicitly enable
+  Alabaster by adding this line to your ``conf.py``:
 
-    * ``pip install alabaster`` or equivalent.
-    * Add the following to your ``conf.py`` so Alabaster's theme location &
-      mini-extension are located & loaded:
+  .. code-block:: python
 
-       .. code-block:: python
+     html_theme = 'alabaster'
 
-            import alabaster
-
-            html_theme_path = [alabaster.get_path()]
-            extensions = ['alabaster']
-            html_theme = 'alabaster'
-
-    * If you've installed Alabaster by hand (without using ``pip``) and/or are
-      doing funky things to your PYTHONPATH, you may need to replace the
-      ``alabaster.get_path()`` call with your own explicit string, as per `the
-      Sphinx config docs
-      <http://sphinx-doc.org/config.html#confval-html_theme_path>`_.
-
-* If you have **Sphinx 1.3 or above**:
-
-    * You already have Alabaster installed as a dependency! No need to manually
-      install it or explicitly load it.
-
-      .. note::
-        If you distribute your documentation via the excellent `Read the Docs
-        <https://readthedocs.org>`_, you may need to explicitly enable
-        Alabaster (as RTD defaults to using its own theme) by adding this line
-        to your ``conf.py``::
-
-            html_theme = 'alabaster'
-
-* **Either way**, add an explicit ``html_sidebars`` setting so Alabaster's
-  customized sidebar templates are loaded:
