+If you want to test the reproducibility of a set of recipes, you can define
+:term:`OEQA_REPRODUCIBLE_TEST_LEAF_TARGETS`, in your local.conf::
+
+   OEQA_REPRODUCIBLE_TEST_LEAF_TARGETS = "my-recipe"
+
+This will test the reproducibility of ``my-recipe`` but will use the
+:ref:`Shared State <overview-manual/concepts:Shared State>` for most its
+dependencies (i.e. the ones explicitly listed in DEPENDS, which may not be all
+dependencies, c.f. [depends] varflags, PACKAGE_DEPENDS and other
+implementations).
+
+You can have finer control on the test with:
+
+- :term:`OEQA_REPRODUCIBLE_TEST_TARGET`: lists recipes to be built,
+- :term:`OEQA_REPRODUCIBLE_TEST_SSTATE_TARGETS`: lists recipes that will
+  be built using :ref:`Shared State <overview-manual/concepts:Shared State>`.
