+# NiceGUI: A Browser Frontend for Your Python Code
+
+Sample scripts for the Real Python NiceGUI tutorial. Each NiceGUI file is a complete app. `generate_password_cli.py` is a plain CLI helper used by the password UI example.
+
+## Setup
+
+These examples need **Python 3.11 or later**. Create a virtual environment and install the dependencies:
+
+```console
+$ python -m venv venv
+$ source venv/bin/activate
+$ python -m pip install -r requirements.txt
+```
+
+On Windows, activate the environment with `venv\Scripts\activate`.
+
+`requirements.txt` installs NiceGUI 3.17.0 with the Plotly extra, along with pinned versions of Plotly, pandas, and [pywebview](https://pywebview.flowrl.com/). `hello_nicegui_native.py` uses pywebview to open a desktop window. On Linux, install a GTK backend as in the tutorial (`pywebview[gtk]` plus the system libraries from the [pywebview installation guide](https://pywebview.flowrl.com/guide/installation.html)).
+
+## Examples
+
+| Script | What it shows |
+| --- | --- |
+| `hello_nicegui.py` | Minimal label and button in the browser |
+| `hello_nicegui_native.py` | Same app in a native desktop window (`native=True`) |
+| `element_catalog.py` | Common inputs and a summary label |
+| `generate_password_cli.py` | CLI password generator |
+| `generate_password_ui.py` | Browser UI that calls the CLI function |
+| `estimate_card.py` | Layout, styling, and a custom color palette |
+| `request_chart.py` | Built-in ECharts bar chart and table |
+| `plotly_chart.py` | Plotly bar chart from a pandas DataFrame |
+
+Run a NiceGUI example from this folder:
+
+```console
+$ python hello_nicegui.py
+```
+
+NiceGUI prints a local URL, usually `http://127.0.0.1:8080`. Open that address in a browser. Stop the app with Ctrl+C.
+
+The native example opens its own window:
+
+```console
+$ python hello_nicegui_native.py
+```
+
+The password CLI works without starting a server:
+
+```console
+$ python generate_password_cli.py -l 24 --symbols
+```
