 ## Quick Start (for development)
 
 ```bash
-# 1. Create and activate a virtual environment
-python -m venv .venv
-source .venv/bin/activate  # On Windows use `.venv\Scripts\activate`
+# 1. Install and use uv (https://github.com/astral-sh/uv)
+uv sync  # creates/updates .venv and installs dependencies

+`uv` pins dependencies in `uv.lock` (exported to `requirements.txt` for compatibility). If you prefer `pip`, you can still do `python -m venv .venv && source .venv/bin/activate` followed by `pip install -r requirements.txt`.

 The SQLite database file is stored in the `instance/` directory (it remains outside of version control by default).
