 ## Environment Setup

+1. We use [uv](https://docs.astral.sh/uv/getting-started/installation/) for managing virtual environments and dependencies.
+   Once uv is installed, run `uv sync` in this repo to get started.
 2. For managing linters, static-analysis, and other tools, we use [pre-commit](https://pre-commit.com/#installation).
    Once Pre-commit is installed, run `pre-commit install` in this repo to install the hooks.
    Using pre-commit ensures PRs match the linting requirements of the codebase.
 
 ## Documentation
 Whenever possible, please add docstrings to your code!
 We use [numpy-style napoleon docstrings](https://sphinxcontrib-napoleon.readthedocs.io/en/latest/#google-vs-numpy).
-To confirm docstrings are valid, build the docs by running `poetry run make html` in the `docs/` folder.
+To confirm docstrings are valid, build the docs by running `uv run make html` in the `docs/` folder.
 
 I typically write dosctrings first, it will act as a guide to limit scope and encourage unit-testable code.
 Good docstrings include information like:
