Detailed Description

This is the implementation of the Mullvad-Leta meta-search engine.

This engine **REQUIRES** that searxng operate within a Mullvad VPN

If using docker, consider using gluetun for easily connecting to the Mullvad

- https://github.com/qdm12/gluetun

Otherwise, follow instructions provided by Mullvad for enabling the VPN on Linux

- https://mullvad.net/en/help/install-mullvad-app-linux

.. hint::

   The :py:obj:`EngineTraits` is empty by default.  Maintainers have to run
   ``make data.traits`` (in the Mullvad VPN / :py:obj:`fetch_traits`) and rebase
   the modified JSON file ``searx/data/engine_traits.json`` on every single
   update of SearXNG!
