🧩 Installation Guide

1. Prepare Server: Create a UTF-8MB4 database; enable required PHP extensions; install Composer and Node.js.
2. Deploy Code: Upload files to the server; run composer install --no-dev and php artisan key:generate.
3. Configure Env: Copy .env.example to .env; set APP_URL, DB credentials, mail (SMTP), cache/queue, and AI provider keys/base URLs.
4. Migrate & Seed: php artisan migrate --seed to create tables and sample roles/templates.
5. Build Frontend: npm install then npm run build (or dev for local testing).
6. Queues & Crons: Start workers with php artisan queue:work; add scheduler via cron (* * * * * php artisan schedule:run).
7. Go Live: Point the domain to public/, enable HTTPS, set secure headers (HSTS/CSP), and verify webhooks (payments).

🧠 Notes

• License: Distributed under the GPL to enable lawful code review, modification, and redistribution per GPL terms.
• Customization Tips: Keep provider logic in dedicated adapters; avoid modifying framework core. Use policies/middleware for per-plan limits.
• Security: Store API keys in env vars; enforce HTTPS, rate limiting, and per-IP throttling; rotate keys regularly.
• Performance: Use Redis cache, enable OPcache, and configure queues for bulk jobs to keep UI responsive.
• SEO Assurance: Clean URLs, meta fields, Open Graph/Twitter cards, XML sitemap hooks, and accessible markup to improve crawlability and UX metrics.
