-====================
-
-SearXNG is a fork of `searx`_, with notable changes:
-
-.. _searx: https://github.com/searx/searx
-
-
-User experience
----------------
-
-- Reworked (and still simple) theme:
-
-  * Usable on desktop, tablet and mobile.
-  * Light and dark versions (available in the preferences).
-  * Right-to-left language support.
-  * `Screenshots <https://dev.searxng.org/screenshots.html>`_
-
-- The translations are up to date, you can contribute on `Weblate`_
-- The preferences page has been updated:
-
-  * Browse which engines are reliable or not.
-  * Engines are grouped inside each tab.
-  * Each engine has a description.
-
-- Thanks to the anonymous metrics, it is easier to report malfunctioning engines,
-  so they get fixed quicker
-
-  - `Turn off metrics on the server
-    <https://docs.searxng.org/admin/engines/settings.html#general>`_ if you don't want them recorded.
-
-- Administrators can `block and/or replace the URLs in the search results
-  <https://github.com/searxng/searxng/blob/5c1c0817c3996c5670a545d05831d234d21e6217/searx/settings.yml#L191-L199>`_

 Setup
------
+=====
 
-- No need for `Morty`_ to proxy images, even on a public instance.
-- No need for `Filtron`_ to block bots, as there is now a built-in `limiter`_.
-- A well maintained `Docker image`_, now also built for ARM64 and ARM/v7 architectures.
-  (Alternatively there are up to date installation scripts.)
