Quick Start

1. Clone this repository.
2. Copy the environment template.
3. Create a MySQL database.
4. Start the app.
5. Open the installer and complete setup.

cp .env.example .env
php -S 127.0.0.1:8080

Windows PowerShell:

Copy-Item .env.example .env
php -S 127.0.0.1:8080

Docker (optional):

docker compose -f docker/docker-compose.yml up -d --build

Installer URL:

• http://127.0.0.1:8080/install

Environment Variables

Set the following in .env:

• JWT_SECRET

• OPENAI_API_KEY
• ANTHROPIC_API_KEY
• DEEPSEEK_API_KEY
• APP_URL

Security Baseline

• Never commit real secrets (.env, API keys, DB passwords, payment private keys)
• Keep APP_DEBUG=false in production
• Use a strong random JWT_SECRET
• Rotate API keys immediately if exposed
• Review AI-generated code before public deployment
