 ## Setting up ROOT
-**TODO**
+
+There are several ways how to setup ROOT. What worked fro me is running the following commands:

+
+delta and lhcba1:
+```
+/cvmfs/sft.cern.ch/lcg/views/setupViews.sh LCG_97python3 x86_64-centos7-gcc9-opt

 In order to make pretty plots, dedicated code in [[Design.cpp|Design.cpp]] is always checked for compilation when starting ROOT. This is done by creating a `.rootalias.C` file in your home directory and telling ROOT to always compile the Design.cpp:
 ```
 {
-gROOT->ProcessLine(".L path/to/your/folder/Code/Design.cpp+");
+gROOT->ProcessLine(".L path/to/your/folder/B2KstarMuMu/Code/Selection/Design.cpp+");
 }
 ```
 
+Anytime you start ROOT by using `root`, the intro printout shows up. I find it useful to set an alias to automatically include the `-l`flag that supresses this output. Open your `~.bashrc` file and add
+```
+alias root="root -l"
+```
+
+If you need to verify the ROOT version at use, open ROOT and run
