# Installation Guide

```{warning}
On Windows, QPE Toolbox is supported only through the Windows Subsystem for Linux (WSL) due to dependency constraints.
```

## Requirements
QPE Toolbox is a pure python library and will run on any system as long as its dependencies support it. In practice, this means any 64-bit macOS or Linux distribution should work. Due to [PySCF restrictions](https://pyscf.org/user/install.html), Windows is only supported through the Windows Subsystem for Linux (WSL).
