 ## Adding deprecation warnings
-The qiskit-qec code is part of Qiskit and, therefore, the [Qiskit Deprecation Policy](https://qiskit.org/documentation/contributing_to_qiskit.html#deprecation-policy) fully applies here. Additionally, qiskit-qec does not allow `DeprecationWarning`s in its testsuite. If you are deprecating code, you should add a test to use the new/non-deprecated method (most of the time based on the existing test of the deprecated method) and alter the existing test to check that the deprecated method still works as expected, [using `assertWarns`](https://docs.python.org/3/library/unittest.html#unittest.TestCase.assertWarns). The `assertWarns` context will silence the deprecation warning while checking that it raises.
