 title: "Instructor Notes"
 ---
-FIXME
+
+This instructure notes are providing information for the instructures of the DASJan2024 and beyond.
+
+## Setup
+
+This version uses the packages in the cvmfs environment `LCG_103`: `/cvmfs/sft.cern.ch/lcg/views/LCG_103/x86_64-centos7-gcc11-opt/setup.sh` 
+In principle, it should work in any computer that has access to cvmfs. 
+
+## Input Files
+
+The nanoAOD files used in the notebooks were copied to the LPC CMSDAS are and are under: `/store/user/cmsdas/2023/short_exercises/jets/`. 
+In principle they need any nanoAOD file for QCD, TTjets, WjetsToQQ and RSGluon.
+
+Currently it uses the TTJets jmenanoAOD to access calojets. 
+
+## Files for CMSSW
+
+The repository contains the old files to run inside CMSSW, and therefore the folder structure
+follows that paradigm. In the current version of this notes, the c++ and python files are there for
+students to look at them if needed. They are not used in the context of the class.
