# Get started with Quantarhei

[Qrhei] is a Python package for calculations of molecular open quantum systems'
dynamics and spectroscopy. It represents a specific take on open quantum
systems, which is explained in the sections below. [Qrhei] wants to help scientists
in this field and promote reproducibility and transparency in both theoretical
and experimental work in the field.

Let's start with the main ideas - philosophy - of this package.
