# 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).
