+---------

+Debug Logs
+^^^^^^^^^^^^^^^
+Run with ``--log-level debug`` to show all debug logs when running ytdl-sub.
+
+
+Reproducing a Failing Subscription
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+Subscriptions will dump their entire *compiled* yaml at the beginning of exeuction
+when using ``--log-level debug``. This can be copy-pasted into the file
+``resources/file_fixtures/repro.yaml``.
+
+Running the test ``e2e.test_debug_repro.TestReproduce.test_debug_log_repro``
+will fully reproduce that subscription in order to debug it.
