# qc-rs — User Manual

Welcome to the **qc-rs user manual** — an educational, textbook-style guide to running quantum-chemistry
calculations with qc-rs, written for newcomers to quantum chemistry, high-performance computing, and
Python alike.

:::{note}
**Draft.** The manual is being written chapter by chapter (design: `.design/78user-manual.md`);
most pages below are still stubs.
