+# How To Install ORCA
+
+## Download the proper ORCA version
+
+Different ORCA version can be downloaded from https://orcaforum.kofo.mpg.de/app.php/dlext/
+To download the software, one must be registered with a PSI account.
+
+For Linux, two different packages are available:
+1. ORCA with dynamically linked serial & parallel binaries linked against OpenMPI vX.Y.Z
+2. ORCA with static serial & parallel binaries linked against OpenMPI vX.Y.Z
+
+For the installation, we will choose the second option: **Static serial & parallel binaries linked against OpenMPI vX.Y.Z**.
+
+## Steps
+
+1. Download the required ORCA version packages (static serial & parallel binaries linked against OpenMPI vX.Y.Z)
+2. ORCA must be used with a OpenMPI version, therefore, we need to create the proper structure for that module.
+   * In example, for `orca/5.0.3`, we will use it with `gcc/11.2.0 openmpi/4.1.3_slurm`.
+   * Therefore, we must create a directory as follows: `mkdir -p /opt/psi/MPI/orca/5.0.3/openmpi/4.1.3_slurm/gcc/11.2.0/share`
+3. Extract the contents of ORCA tar files to the corresponding directory in ` /opt/psi/MPI/orca/$version/openmpi/4.1.3_slurm/gcc/11.2.0`
+4. Run the post-installation step
+
+## Post-Installation step
+
+1. Add the new version in the variants file, including `openmpi` dependencies:
+   ```bash
+   (base) [caubet_m-adm@merlin-l-001 orca]# git diff files/variants.rhel7
+   orca/5.0.3     unstable   gcc/11.2.0 openmpi/4.1.3_slurm
+   ```
+2. Update Module files:
+   ```bash
+   (base) [caubet_m-adm@merlin-l-001: orca]# ./build 5.0.3 --system=merlin6 --update-modulefiles 
+   orca/5.0.3: with gcc/11.2.0 openmpi/4.1.3_slurm building ... 
+   Loading module: gcc/11.2.0
+   Loading module: openmpi/4.1.3_slurm
+   module load: unstable module has been loaded -- openmpi/4.1.3_slurm
+   orca/5.0.3: with gcc/11.2.0 openmpi/4.1.3_slurm already exists, not rebuilding ... 
+   orca/5.0.3: installing modulefile '/opt/psi/MPI/modulefiles/gcc/11.2.0/openmpi/4.1.3_slurm/orca/5.0.3' ... 
+   * * * * *
+   ```
+3. Add `.info` file
+   ```bash
+   (base) [caubet_m-adm@merlin-l-001 orca]# cat /opt/psi/MPI/orca/5.0.3/openmpi/4.1.3_slurm/gcc/11.2.0/.info 
+   ORCA is only allowed to be used for PSI's own internal, non-commercial
+   scientific activities.
+   
+   Each user (employees, contractors, students) must register on the ORCA
+   website (https://orcaforum.kofo.mpg.de/app.php/portal) with a PSI Email
+   address.
+   
+   For further information, please read:
+   /opt/psi/MPI/orca/5.0.3/openmpi/4.1.3_slurm/gcc/11.2.0/bin/EULA_ORCA_2021.pdf
+   ```

+ORCA is a flexible, efficient and easy-to-use general purpose tool for
+quantum chemistry with specific emphasis on spectroscopic properties of
+open-shell molecules. It features a wide variety of standard quantum 
+chemical methods ranging from semiempirical methods to DFT to single- 
+and multireference correlated ab initio methods. It can also treat 
+environmental and relativistic effects.
+
+Due to the user-friendly style, ORCA is considered to be a helpful tool
+not only for computational chemists, but also for chemists, physicists 
+and biologists that are interested in developing the full information 
+content of their experimental data with help of calculations.
