+Partner attribution
+===================
+.. _partner attribution:
+
+In contrast to :ref:`partner repacks`, attributed builds only differ from the normal Firefox
+builds by the adding a string in the dummy windows signing certificate. We support doing this for
+full installers but not stub. The parameters of the string are carried into the telemetry system,
+tagging an install into a cohort of users. This a lighter weight process because we don't
+repackage or re-sign the builds.
+
+Parameters & Scheduling
+-----------------------
+
+Partner attribution uses a number of parameters to control how they work:
+
+* ``release_enable_partner_attribution``
+* ``release_partner_config``
+* ``release_partner_build_number``
+* ``release_partners``
+
+The enable parameter is a boolean, a simple on/off switch. We set it in shipit's
+`is_partner_enabled() <https://github.com/mozilla-releng/shipit/blob/main/api/src/shipit_api/admin/release.py#L93>`_ when starting a
+release. It's true for Firefox betas >= b8 and releases, but otherwise false, the same as
+partner repacks.
+
+``release_partner_config`` is a dictionary of configuration data which drives the task generation
+logic. It's usually looked up during the release promotion action task, using the Github
+GraphQL API in the `get_partner_config_by_url()
+<python/taskgraph.util.html#taskgraph.util.partners.get_partner_config_by_url>`_ function, with the
+url defined in `taskcluster/ci/config.yml <https://searchfox.org/mozilla-central/search?q=partner-urls&path=taskcluster%2Fci%2Fconfig.yml&case=true&regexp=false&redirect=true>`_.
+
+``release_partner_build_number`` is an integer used to create unique upload paths in the firefox
+candidates directory, while ``release_partners`` is a list of partners that should be
+attributed (i.e. a subset of the whole config). Both are intended for use when respinning a partner after
+the regular Firefox has shipped. More information on that can be found in the
+`RelEng Docs <https://moz-releng-docs.readthedocs.io/en/latest/procedures/misc-operations/off-cycle-partner-repacks-and-funnelcake.html>`_.
+
+``release_partners`` is shared with partner repacks but we don't support doing both at the same time.
+
+
+Configuration
+-------------
+
+This is done using an ``attribution_config.yml`` file which next lives to the ``default.xml`` used
+for partner repacks. There are no repos for each partner, the whole configuration exists in the one
+file because the amount of information to be tracked is much smaller.
+
+An example config looks like this:
+
+.. code-block:: yaml
+
+    defaults:
+        medium: distribution
+        source: mozilla
+    configs:
+        -   campaign: sample
+            content: sample-001
+            locales:
+            - en-US
+            - de
+            - ru
+            platforms:
+            - win64-shippable
+            - win32-shippable
+            upload_to_candidates: true
+
+The four main parameters are ``medium, source, campaign, content``, of which the first two are
+common to all attributions. The combination of ``campaign`` and ``content`` should be unique
+to avoid confusion in telemetry data. They correspond to the repo name and sub-directory in partner repacks,
+so avoid any overlap between values in partner repacks and atrribution.
+The optional parameters of ``variation``, and ``experiment`` may also be specified.
+
+Non-empty lists of locales and platforms are required parameters (NB the `-shippable` suffix should be used on
+the platforms).
+
+``upload_to_candidates`` is an optional setting which controls whether the Firefox installers
+are uploaded into the `candidates directory <https://archive.mozilla.org/pub/firefox/candidates/>`_.
+If not set the files are uploaded to the private S3 bucket for partner builds.
+
+
+Repacking process
+-----------------
+
+Attribution only has two kinds:
+
+* attribution - add attribution code to the regular builds
+* beetmover - move the files to a partner-specific destination
+
+Attribution
+^^^^^^^^^^^
+
+* kinds: ``release-partner-attribution``
+* platforms: Any Windows, runs on linux
+* upstreams: ``repackage-signing`` ``repackage-signing-l10n``
+
+There is one task, calling out to `python/mozrelease/mozrelease/partner_attribution.py
+<https://hg.mozilla.org/releases/mozilla-release/file/default/python/mozrelease/mozrelease/partner_attribution.py>`_.
+
+It takes as input the repackage-signing and repackage-signing-l10n artifacts, which are all
+target.exe full installers. The ``ATTRIBUTION_CONFIG`` environment variable controls the script.
+It produces more target.exe installers.
+
+The size of ``ATTRIBUTION_CONFIG`` variable may grow large if the number of configurations
+increases, and it may be necesssary to pass the content of ``attribution_config.yml`` to the
+script instead, or via an artifact of the promotion task.
+
+Beetmover
+^^^^^^^^^
+
+* kinds: ``release-partner-attribution-beetmover``
+* platforms: N/A, scriptworker
+* upstreams: ``release-partner-attribution``
+
+Moves and renames the artifacts to their public location in the `candidates directory
+<https://archive.mozilla.org/pub/firefox/candidates/>`_, or a private S3 bucket. There is one task
+for public artifacts and another for private.
+
+Each task will have the ``project:releng:beetmover:action:push-to-partner`` scope, with public uploads having
+``project:releng:beetmover:bucket:release`` and private uploads using
+``project:releng:beetmover:bucket:partner``. There's a partner-specific code path in
+`beetmoverscript <https://github.com/mozilla-releng/scriptworker-scripts/tree/master/beetmoverscript>`_.
