+## Instruction to produce modified nanoAOD with the jetToolbox (beta version)
+
+This is a beta version on how to modify nanoAOD production to incorporate different jet collections in nanoAOD format. This will create the standard nanoAOD variables plus new variables run by the jetToolbox.
+
+The only file that needs to be modified is [JMEAnalysis/JetToolbox/python/nanoAOD_jetToolbox_cff.py](python/nanoAOD_jetToolbox_cff.py), using the same setting as in the miniAOD case.
+*The main change is the dataTier parameter, in case of nanoAOD:* `dataTier="nanoAOD"`.
+After modify the `setupCustomizedJetToolbox` function in that file, one can run a cmsDriver command. For instance (for nanoAOD v5 2018):
+
+~~~
+cmsDriver.py nanoAOD_jetToolbox_cff -s NANO --mc --eventcontent NANOAODSIM --datatier NANOAODSIM --no_exec --conditions 102X_upgrade2018_realistic_v19 --era Run2_2018,run2_nanoAOD_102Xv1 --customise_commands="process.add_(cms.Service('InitRootHandlers', EnableIMT = cms.untracked.bool(False)))" --customise JMEAnalysis/JetToolbox/nanoAOD_jetToolbox_cff.nanoJTB_customizeMC --filein /store/mc/RunIIAutumn18MiniAOD/TTJets_TuneCP5_13TeV-amcatnloFXFX-pythia8/MINIAODSIM/102X_upgrade2018_realistic_v15_ext1-v2/20000/7E65457A-87E5-C146-8321-9A48B4F56ED1.root --fileout file:jetToolbox_nano_mc.root
+~~~
+
+Notice that the `--customise` option points to the file [JMEAnalysis/JetToolbox/python/nanoAOD_jetToolbox_cff.py](python/nanoAOD_jetToolbox_cff.py). 
+
+
+A working example, after running the cmsDriver command shown above, is located here: [JMEAnalysis/JetToolbox/test/jetToolbox_nanoAODv05_cfg.py](test/jetToolbox_nanoAODv05_cfg.py). 
+
+All the variables created by the jetToolbox start with `selectedPatJets**`.
