 ### Notes
 
-(1) You can substitute `--monkey` with `--ape`, `--combo`, `--qtesting` or `--timemachine` to directly run the corresponding tool. You may need to change the output directory `-o ../monkey-results/` to a distinct directory, e.g., `-o ../ape-results`. You can follow the similar steps described above to inspect whether the target bug was found or not and the related info.
