+- If it's just a tool to help you code → `[project.optional-dependencies].dev`

 1. Install the following:

+    - [Python 3.11+](https://www.python.org/downloads/)
-    - [Poetry](https://python-poetry.org/docs/#installing-with-the-official-installer)

+    ```bash
+    python -m venv .venv
+    # On Windows
+    .venv\Scripts\activate
+    # On macOS/Linux
+    source .venv/bin/activate
+
+    pip install --upgrade pip
+    pip install .[dev]
+    ```
+
+**What this installs:**
+- All the packages your function needs to run (`dependencies`)
+- Plus development tools like testing and code formatting (`[project.optional-dependencies].dev`)
+
+**Why separate sections?**
+- `dependencies`: Only what gets deployed with your function (lightweight)
+- `dev` dependencies: Extra tools to help you write better code locally
 
 ## Building and Testing

+### Alternative dependency managers
+
+This template uses the modern **PEP 621** standard in `pyproject.toml`, which works with all modern Python dependency managers:
+
+#### Using Poetry
+```bash
+poetry install  # Automatically reads pyproject.toml
+```
+
+#### Using uv
+```bash
+uv sync  # Automatically reads pyproject.toml
+```
+
+#### Using pip-tools
+```bash
+pip-compile pyproject.toml  # Generate requirements.txt from pyproject.toml
+pip install -r requirements.txt
+```
+
+#### Using pdm
+```bash
+pdm install  # Automatically reads pyproject.toml
+```
+
+**Advantage**: All tools read the same `pyproject.toml` file, so there's no need to keep multiple files in sync!
