 ## Features
 
+- **Application Deployment**: Deploy complete applications with a single method call
+- **Environment Variables & Labels**: Configure containers with environment variables and Kubernetes labels
+- **Resource Lifecycle Management**: Automatic cleanup and replacement of existing resources
 - **Namespace-scoped Management**: Each `KubernetesManager` instance operates on a single namespace
 - **Pod Management**: List, create, and manage pods
 - **Pattern-based Deletion**: Delete resources using PCRE pattern matching
 - **Namespace Operations**: Create and manage namespaces (idempotent operations)
 - **Resource Management**: Support for pods, services, deployments, configmaps, secrets, and more
-- **Rhai Integration**: Full scripting support through Rhai wrappers
+- **Rhai Integration**: Full scripting support through Rhai wrappers with environment variables

+### Labels vs Environment Variables
+
+Understanding the difference between labels and environment variables is crucial for effective Kubernetes deployments:
+
+#### **Labels** (Kubernetes Metadata)
+
+- **Purpose**: Organize, select, and manage Kubernetes resources
+- **Scope**: Kubernetes cluster management and resource organization
+- **Visibility**: Used by Kubernetes controllers, selectors, and monitoring systems
+- **Examples**: `app=my-app`, `tier=backend`, `environment=production`, `version=v1.2.3`
+- **Use Cases**: Resource grouping, service discovery, monitoring labels, deployment strategies
+
+#### **Environment Variables** (Container Configuration)
+
+- **Purpose**: Configure application runtime behavior and settings
+- **Scope**: Inside container processes - available to your application code
+- **Visibility**: Accessible via `process.env`, `os.environ`, etc. in your application
+- **Examples**: `NODE_ENV=production`, `DATABASE_URL=postgres://...`, `API_KEY=secret`
+- **Use Cases**: Database connections, API keys, feature flags, runtime configuration
+
+#### **Example: Complete Application Configuration**
+
+```rust
+// Labels: For Kubernetes resource management
+let mut labels = HashMap::new();
+labels.insert("app".to_string(), "web-api".to_string());           // Service discovery
+labels.insert("tier".to_string(), "backend".to_string());         // Architecture layer
+labels.insert("environment".to_string(), "production".to_string()); // Deployment stage
+labels.insert("version".to_string(), "v2.1.0".to_string());       // Release version
+
+// Environment Variables: For application configuration
+let mut env_vars = HashMap::new();
+env_vars.insert("NODE_ENV".to_string(), "production".to_string());              // Runtime mode
+env_vars.insert("DATABASE_URL".to_string(), "postgres://db:5432/app".to_string()); // DB connection
+env_vars.insert("REDIS_URL".to_string(), "redis://cache:6379".to_string());     // Cache connection
+env_vars.insert("LOG_LEVEL".to_string(), "info".to_string());                   // Logging config
+```
 
 ## Usage
 
+### Application Deployment (Recommended)
+
+Deploy complete applications with labels and environment variables:
+
+```rust
+use sal_kubernetes::KubernetesManager;
+use std::collections::HashMap;
+
+#[tokio::main]
+async fn main() -> Result<(), Box<dyn std::error::Error>> {
+    let km = KubernetesManager::new("default").await?;
+
+    // Configure labels for Kubernetes resource organization
+    let mut labels = HashMap::new();
+    labels.insert("app".to_string(), "my-app".to_string());
+    labels.insert("tier".to_string(), "backend".to_string());
+
+    // Configure environment variables for the container
+    let mut env_vars = HashMap::new();
+    env_vars.insert("NODE_ENV".to_string(), "production".to_string());
+    env_vars.insert("DATABASE_URL".to_string(), "postgres://db:5432/myapp".to_string());
+    env_vars.insert("API_KEY".to_string(), "secret-api-key".to_string());
+
+    // Deploy application with deployment + service
+    km.deploy_application(
+        "my-app",           // name
+        "node:18-alpine",   // image
+        3,                  // replicas
+        3000,               // port
+        Some(labels),       // Kubernetes labels
+        Some(env_vars),     // container environment variables
+    ).await?;

-## Security Considerations
+### Test Requirements
+
+- **Kubernetes Cluster**: Integration tests require a running Kubernetes cluster
+- **Environment Variable**: Set `KUBERNETES_TEST_ENABLED=1` to enable integration tests
+- **Permissions**: Tests require permissions to create/delete resources in the `default` namespace
+
+## Production Considerations
+
+### Security
 
 - Always use specific PCRE patterns to avoid accidental deletion of important resources
 - Test deletion patterns in a safe environment first
 - Ensure proper RBAC permissions are configured
 - Be cautious with cluster-wide operations like namespace listing
-- Consider using dry-run approaches when possible
+- Use Kubernetes secrets for sensitive environment variables instead of plain text
+
+### Performance & Scalability
+
+- Consider adding resource limits (CPU/memory) for production deployments
+- Use persistent volumes for stateful applications
+- Configure readiness and liveness probes for health checks
+- Implement proper monitoring and logging labels
+
+### Environment Variables Best Practices
+
+- Use Kubernetes secrets for sensitive data (passwords, API keys)
+- Validate environment variable values before deployment
+- Use consistent naming conventions (e.g., `DATABASE_URL`, `API_KEY`)
+- Document required vs optional environment variables
+
+### Example: Production-Ready Deployment
+
+```rust
+// Production labels for monitoring and management
