 ## Running locally
 
 1. Clone the repo
 2. Install the dependencies, preferably in a venv:
    ```shell
-   python3 -m venv venv
-   source ./venv/bin/activate
-   pip3 install -r requirements.txt
+   uv venv --python 3.14 --seed
+   source .venv/bin/activate
+   uv pip install -r requirements.txt
    ```
 3. Copy [example.env](example.env) to `.env`, customize it.
 4. Source `.env`:
