 # nestforge-config
 
-Environment configuration loading and validation utilities for NestForge.
+A NestJS-inspired configuration module for NestForge applications.
 
-- Repository: https://github.com/vernonthedev/nestforge
-- Docs: https://github.com/vernonthedev/nestforge/wiki
+## Features
+
+- **Type-safe configuration** - Get typed values from environment variables
+- **NestJS-like API** - Familiar patterns for NestJS developers
+- **DI Integration** - Seamlessly works with NestForge's dependency injection
+- **Simple getters** - No unwrap_or chains, just `get_string_or("KEY", "default")`
+- **Dotenv support** - Automatic loading from `.env` files
+
+## Quick Start
+
+```rust
+use nestforge_config::{ConfigService, ConfigModule};
+
+pub type AppConfig = ConfigService;
+
+pub fn load_config() -> AppConfig {
+    ConfigModule::for_root_with_options(ConfigModule::for_root().env_file(".env"))
+}
+```
+
+## Usage in Services
+
+```rust
+use nestforge::prelude::*;
+
+pub struct MyService {
+    config: Config<AppConfig>,
+}
+
+impl MyService {
+    pub fn do_something(&self) {
+        let app_name = self.config.get_string_or("APP_NAME", "My App");
+        let port = self.config.get_u16_or("PORT", 3000);
+        let debug = self.config.get_bool_or("DEBUG", false);
+    }
+}
+```
+
+## Available Methods
+
+| Method | Description |
+|--------|-------------|
+| `get_string("KEY")` | Get string (default: `""`) |
+| `get_string_or("KEY", "default")` | Get with default |
+| `get_u16("KEY")` | Get u16 (default: `0`) |
+| `get_u16_or("KEY", 3000)` | Get with default |
+| `get_bool("KEY")` | Get bool (default: `false`) |
+| `get_bool_or("KEY", true)` | Get with default |
+| `get("KEY")` | Get `Option<&str>` |
+| `has("KEY")` | Check if key exists |
