 ## Installation
-To install the library locally, clone the repo down and install dependencies with [Poetry](https://python-poetry.org/).
+The package is published on [PyPI](https://pypi.org/project/ursina-proteins/), and can be installed with `pip install ursina-proteins`.
+You can also clone the repo down and install dependencies with [Poetry](https://python-poetry.org/).

 ## Usage
-You can use the library in an existing Ursina project by importing the Protein class and creating an instance from a PDB file. You can render any proteins in the PDB file format, and can find many available for download at the [RCSB Protein Data Bank](https://www.rcsb.org/).
