 ## Installation

+In general, it is recommended that you install the software on a fast disk to ensure fast compilation (e.g. AFS), but that you process the heavy n-tuples on a dedicated area (e.g. NFS at DESY, EOS at CERN). Keeping the software neat and clean is important for reproducibility.

-#### Remarks
-
-1. You may overwrite (at your own risks) the CMSSW release by running `make CMSSW=CMSSW_X_Y_Z` where you tune `X`, `Y`, and `Z` to the values of the release that you want to test. This may be necessary to run over certain data sets; however, we cannot guarantee that the code will compile nor provide the same result as in the default release.
-2. `git-cms-init` is not run, since it is a priori not useful for the framework to run, takes 100MB of space, and makes the installation slower. If it may happen to be useful, you have to add it in the Makefile. It must be run right after setting up the release, when it is locally still empty.
-3. To use SSH instead of HTTPS, run `make GITLAB=ssh://git@gitlab.cern.ch:7999`.
-4. The `PlottingHelper` is not cloned by default as it is only useful for plotting purposes.
+*Remark*: if a CMSSW release has already been sourced, it will use that one instead of installing a new one.
+3. Then change to the directory of the CMSSW release (by default, it is created in the local directory) and compile as follows:
+```
+cmsenv
+scram b -j$(nproc)
+```
+4. After a few minutes, you're all set. You may have to rerun `cmsenv` to actually see the commands in the shell.
 
-### From an existing CMSSW release or from an existing installation.
+### By hand, step by step
 
 In the following, we explain the installation of the framework step by step. A few packages external to CMSSW are necessary (e.g. TUnfold), which you will need to tell CMSSW how to find them with `scram setup`.
