-# sld-php-template
+# SLD PHP Template
 
-Basic php framework for php plain websites.
+A lightweight and modular PHP starter framework for building plain PHP websites without heavy dependencies.
+
+This project is designed to provide a clean structure, reusable components, and a simple initialization system to speed up development while keeping full control over the codebase.
+
+---
+
+## 🚀 Features
+
+- ⚡ Lightweight and fast (no external frameworks required)
+- 📁 Clean and scalable folder structure
+- 🔧 Centralized configuration system
+- 🧩 Modular templates (header, footer, includes)
+- 🎨 Basic frontend setup (CSS variables, animations, JS helpers)
+- 🛠 Ready-to-use initialization system
+- ❌ Built-in error pages (environment & database)
+

+├── assets/
+│   ├── css/

+├── pages/
+├── templates/
+├── themes/
+├── public/
+├── index.php
+└── README.md
+```
+
+---
+
+## ⚙️ Configuration
+
+All core configuration is located inside the `config/` directory:
+
+- `init.php` → Application bootstrap
+- `constants.php` → Global constants
+- `settings.php` → App settings
+- `db.php` → Database connection
+- `functions_init.php` → Function loader
+
+---
+
+## 🧠 How It Works
+
+1. The application starts from `index.php`
+2. Core initialization is handled by the config system
+3. Templates are loaded dynamically (`header.php`, `footer.php`)
+4. Pages are rendered from the `pages/` directory
+5. Custom logic can be added via the `functions/` folder
+
+---
+
+## 🎨 Frontend
+
+The project includes a minimal frontend setup:
+
+### CSS System
+- Variables-based color system with multiple shades
+- Basic layout styles
+- Animation utilities
+
+### JavaScript
+- Simple helper functions like dynamic year rendering
+
+---
+
+## 🛠 Usage
+
+1. Clone the repository:
+   ```bash
+   git clone https://github.com/your-username/sld-php-template.git
+   ```
+
+2. Move it into your web server directory
+
+3. Configure:
+   - Database (`config/db.php`)
+   - Environment settings (`config/settings.php`)
+
+4. Open in browser:
+   ```
+   http://localhost/your-project
+   ```
+
+---
+
+## 📄 Pages
+
+- `home.php` → Main homepage
+- `db-error.php` → Database error page
+- `env-error.php` → Environment error page
+
+---
+
+## 🧩 Templates
+
+Reusable layout components:
+
+- `templates/header.php`
+- `templates/footer.php`
+
+---
+
+## 🧪 Status
+
+🚧 This project is currently in development.  
+New features and improvements will be added progressively.
+
+---
+
+## 📌 Roadmap (Planned)
+
+- [ ] Routing system
+- [ ] Theme engine
+- [ ] Admin panel structure
+- [ ] CLI tools
+- [ ] Environment (.env) support
+- [ ] Basic authentication system
