 **Step 2**: use the `crab.py` script to submit the CRAB jobs:
 
 For MC:
 
 ```bash
-python crab.py -p mc_NANO.py -o /store/group/lpcjme/noreplica/NanoHRT/mc/[version] -t NanoTuples-[version] -i mc_[ABC].txt --num-cores 4 --send-external -s EventAwareLumiBased -n 50000 --work-area crab_projects_mc_[ABC]
+python crab.py -p mc_NANO.py -o /store/group/lpcjme/noreplica/NanoHRT/mc/[version] -t NanoTuples-[version] -i mc_[ABC].txt --num-cores 4 --send-external -s EventAwareLumiBased -n 50000 --work-area crab_projects_mc_[ABC] --dryrun
 ```
 
 For data:
 
 ```bash
-python crab.py -p data_NANO.py -o /store/group/lpcjme/noreplica/NanoHRT/data/[version] -t NanoTuples-[version] -i data.txt --num-cores 4 --send-external -s EventAwareLumiBased -n 50000 --work-area crab_projects_data

 ```
 
 A JSON file can be applied for data samples with the `-j` options. By default, we use the golden JSON for 2016:

-**[Note]** Before actual submission, you can add the `--dryrun` option to print out the CRAB configuration to see if everything is correct.
-
+These command will perform a "dryrun" to print out the CRAB configuration files. Please check everything is correct (e.g., the output path, version number, requested number of cores, etc.) before submitting the actual jobs. To actually submit the jobs to CRAB, just remove the `--dryrun` option at the end.
 
 **Step 3**: check job status
