+
+## Features
+

+- Highlights the next upcoming week automatically
+- Supports theme switching in the UI
+- Loads schedule data from Google Sheets CSV export or local fallback JSON
+- Provides an API endpoint for schedule data
+
+## Requirements
+
+- Python 3.13+ (recommended)
+
+## Local Development
+
+1. Install dependencies using UV
 
-# Development
-1. Install requirements
 ```bash
-python3 -m pip install -r requirements.txt
-```
-2. Run the dev server
-```bash
-python3 server.py
+uv sync
 ```
 
-# Production
-Run using the main.py file
+2. Start the development server:
+
 ```bash
-python3 main.py
-```
+uv run main.py
+```
+
+3. Open:
+
+```text
+http://127.0.0.1:5000
+```
+
+## Production Run
+
+Run with Gunicorn via the included launcher:
+
+```bash
+uv run main.py
+```
+
+Default bind address is `0.0.0.0:5000`.
+
+## Configuration
+
+Use a `.env` file or environment variables.
+
+- `GOOGLE_SHEET_URL`: Optional. If set, schedule data is fetched from Google Sheets.
+- `WORKERS`: Optional Gunicorn worker count (default: `1`).
+- `THREADS`: Optional Gunicorn thread count (default: `2`).
+
+If `GOOGLE_SHEET_URL` is not set or fetch/parsing fails, the app falls back to `schedule_data.json` if present.
