The theme is available on PyPI and conda-forge, and can thus be installed with:

$ pip install pydata-sphinx-theme
$ conda install pydata-sphinx-theme --channel conda-forge

Then, in the of your sphinx docs, you update the html_theme configuration option:

html_theme = "pydata_sphinx_theme"

If you want to track the development version of the theme, you can install it from the git repo:

$ pip install git+

or in a conda environment yml file, you can add:

- pip:
  - git+
