 This is an effort to produce high quality HTML documentation for GNU social in English.
 
-To build the documentation simply run `php render.php`. The output HTML will be in the `rendered/` subfolder.
+The documentation is produced using Python Sphinx, which uses a lightweight text-based markup.
+
+To build the documentation see README.sphinx.
 
 Rendered versions are available online:
 
 - User Guide - <https://karp.id.au/social/user/>
 - Admin Guide - <https://karp.id.au/social/admin/>
 
-## Editing
-
-- Add or edit HTML in `html/user/` or `html/admin`
-- Add or edit images, etc., in `resources/user/` or `resources/admin`
-- Ensure the page listing is up-to-date in `configs/user.config.php` and `configs/admin.config.php`
-- Run `php render.php` and check it worked
-- Submit a pull request so everybody gets smarter
-
-Various template substitutions are available. These are the most important ones.
-
-    {HEADING:SECTION:section:My Heading}             -- becomes an <h2> with internal name "section"
-    {HEADING:SUBSECTION:subsection:My subheading}    -- becomes an <h3> with internal name "subsection"
-    {LINK:section}                                   -- becomes an <a> to appropriate_page.html#section
