# StackIt - Q&A Platform using Flask + PostgreSQL
# Step-by-step setup starting here.

# First, we set up the Flask project directory structure
# Folder structure:
# stackit/
# ├── app/
# │   ├── __init__.py
# │   ├── models.py
# │   ├── routes.py
# │   ├── templates/
# │   ├── static/
# ├── config.py
# ├── run.py
# ├── requirements.txt
# └── README.md

# Step 1: Create virtual environment and install dependencies
# Run these commands in terminal:
# python3 -m venv venv
# source venv/bin/activate  (on macOS/Linux)
# pip install flask flask_sqlalchemy psycopg2-binary flask-login
# pip freeze > requirements.txt

# Step 2: Create config.py to hold database URI and app config

# config.py
