quack/INSTALL.md

The QuAcK software can be downloaded on GitHub as a Git repository

git clone https://github.com/pfloos/QuAcK.git

Then, one must define the variable QUACK_ROOT. For example,

export QUACK_ROOT=$HOME/Work/QuAcK

You must also install PySCF (for example using pip)

pip install pyscf

PySCF is used for the computation of one- and two-electron integrals (mainly).
