+In tech policy, you know the value of containment. We don't want to install software libraries globally where they might break other things. We use **UV**—a modern, fast Python package manager that handles everything for us: creating a sandbox, installing the right Python version, and fetching dependencies.
+
+* *Concept:* **UV** is like a smart assistant that sets up your entire Python environment automatically. It reads a "shopping list" called `pyproject.toml` and fetches everything you need in one command.
+
+**Installing UV:**
 
 **On Windows (PowerShell):**
 
 ```powershell
-python -m venv venv
-.\venv\Scripts\activate
-
+powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"
 ```
 
+After installation, **close and reopen PowerShell** for the changes to take effect.
+
 **On Mac/Linux (Terminal):**
 
 ```bash
-python3 -m venv venv
-source venv/bin/activate
-
+curl -LsSf https://astral.sh/uv/install.sh | sh
 ```
 
-*Check:* You should see `(venv)` appear at the start of your command prompt line. You are now inside the sandbox.
+After installation, either restart your terminal or run:
+```bash
+source $HOME/.local/bin/env
+```
 
-#### 5. Install Dependencies (The "Pip" Step)
+*Check:* Type `uv --version` and press Enter. You should see a version number like `uv 0.5.x`. If you see "command not found", try restarting your terminal.
 
-We need to equip our sandbox with specific tools like `streamlit` (for the website) and `duckdb` (for the database). To do this, we use **pip**.
+#### 5. Install Dependencies (The "UV Sync" Step)
 
-* *Concept:* **Pip** is the App Store installer for Python. Instead of browsing a store, we give it a shopping list called `requirements.txt`, and it fetches everything for us automatically.
+Now we use UV to create our sandbox and install all the tools we need (like `streamlit` for the website and `duckdb` for the database).
 
-Run this command:
+Run this command from inside the project folder:
 
 ```bash
-pip install -r requirements.txt
-
+uv sync
 ```
 
+*What just happened?* UV did several things automatically:
+1. Created a `.venv` folder (the sandbox)
+2. Installed the correct Python version if needed
+3. Downloaded and installed all the required libraries
+
+*Check:* You should see output showing packages being installed. When it's done, you'll see something like "Resolved X packages" and "Installed X packages".

 **Save the file** if you made any changes. Now, run the app from your CLI:

+*Note:* We use `uv run` to execute commands inside our sandbox. This ensures Streamlit uses the correct Python environment with all our installed dependencies.
