+App store redirects
+-------------------
+
+Occasionally we need to create a link that can auto redirect to either the Apple
+App Store or the Google Play Store depending on user agent. A common use case is
+to embed inside a QR Code, which people can then scan on their phone to get a
+shortcut to the app. To make this easier bedrock has a special redirect URL to
+which you can add product and campaign query strings. When someone hits the
+redirect URL, bedrock will attempt to detect their mobile platform and then auto
+redirect to the appropriate app store.
+
+The base redirect URL is ``https://www.mozilla.org/firefox/browsers/mobile/app/``,
+and to it you can add both a ``product`` and ``campaign`` query parameter. For
+example, the following URL would redirect to either Firefox on the Apple App Store
+or on the Google Play Store, with the specified campaign parameter.
+
+.. code-block::
+
+    https://www.mozilla.org/firefox/browsers/mobile/app/?product=firefox&campaign=firefox-whatsnew
+
+.. note::
+
+    The ``product`` and ``campaign`` parameters are limited to a set of strictly
+    trusted values. To add more product and campaign options, you can add those
+    values to the ``mobile_app`` helper function in
+    `firefox/redirects.py <https://github.com/mozilla/bedrock/blob/main/bedrock/firefox/redirects.py>`_.
