+### Using cache to continue aborted experiment
+
+**[Experimental feature]** Sometimes long-running (expensive) ICAI experiments get interrupted. Instead of requiring a full re-run, the ICAI package supports continuing certain experiments after they were interupted. This feature is only available for the voting stage of experiments: only for experiments that do not generate principles but use a pre-existing principle list to test.
+
+To re-start an experiment with log dir `exp/outputs/prior-experiment` and config dir `exp/configs/exp-config`, use the following command:
+```
+icai-exp -cd exp/configs/prior-experiment prior_cache_path='exp/outputs/prior-experiment'
+```
+>[!WARNING]
+> Note that there is no strict config consistency check between cache and new experiment - thus use with caution, only using caches from prior experiments with identical configs.
