Shield Recipe Client
====================

Normandy (aka the Shield Recipe Client) is a targeted change control
system, allowing small changes to be made within a release of Firefox,
such as studies.

It downloads recipes and actions from :ref:`Remote Settings <services/remotesettings>`
and then executes them.

.. note::

   Previously, the recipes were fetched from the `recipe server`_, but in `Bug 1513854`_
   the source was changed to *Remote Settings*. The cryptographic signatures are verified
   at the *Remote Settings* level (integrity) and at the *Normandy* level
   (authenticity of publisher).
