   * For each task in the panel (e.g. `loop invariant preservation`), you can right-click it and run the prover.
+    * Important: The prover might not be able to verify the correct solution if the number of steps is too small. Make sure to test with 1000~5000 steps.
   * Fill in `TODO`s until the prover can verify all tasks, notified with green check-marks.
