# Installation instructions¶

There are several ways to install TeNPy.

A very comfortable way is to simply use [pip] with:

pip install physics-tenpy


More details for this method can be found in Installation from PyPi with pip.

We also have a bunch of optional Extra requirements, which you don’t have to install to use TeNPy, but you might want to.

The method with the minimal requirements is to just download the source and adjust the PYTHONPATH, as described in Installation from source. This is also the recommended way if you plan to modify parts of the source.
