-```
-
-## Usage
-
-`@push.rocks/smartlog` is a flexible, extensible logging tool designed for distributed systems. It provides a consistent logging interface across different environments while being lightweight and customizable.
-
-### Creating a Logger Instance
-
-Start by importing `Smartlog` and create a logger instance:
 
 ```typescript
 import { Smartlog } from '@push.rocks/smartlog';
 
+// Create a logger with context
 const logger = new Smartlog({
   logContext: {
-    company: 'My Company',
+    company: 'MyStartup',
-    companyunit: 'Cloud Team',
+    companyunit: 'Backend Team',
-    containerName: 'api-service',
+    containerName: 'api-gateway',
-    environment: 'production', // 'local', 'test', 'staging', 'production'
+    environment: 'production',
-    runtime: 'node',           // 'node', 'chrome', 'rust', 'deno', 'cloudflare_workers'
+    runtime: 'node',
-    zone: 'us-west',
+    zone: 'eu-central'
-  },
+  }
-  minimumLogLevel: 'info',     // Optional, defaults to 'silly'
 });
 
-// Enable console output
+// Enable beautiful console output
 logger.enableConsole();
+
+// Start logging!
+logger.log('info', '🎉 Application started successfully');
+logger.log('error', '💥 Database connection failed', { 
+  errorCode: 'DB_TIMEOUT',
+  attemptCount: 3 
+});
 ```
 
-The context enriches logs with valuable information for filtering and analysis across distributed systems.
+### Using the Default Logger
 
-### Logging Messages
+For quick prototyping and simple applications:
-
-```typescript
-// Basic logging
-logger.log('info', 'User authenticated successfully');
-logger.log('error', 'Database connection failed', { errorCode: 'DB_CONN_ERR', retryCount: 3 });
-logger.log('warn', 'Rate limit approaching', { currentRate: 95, limit: 100 });
-
-// Log levels: 'silly', 'info', 'debug', 'note', 'ok', 'success', 'warn', 'error', 'lifecycle'
-```
-
-The third parameter accepts any additional data to attach to the log entry.
-
-### Default Logger
-
-For simple cases, use the built-in default logger:
 
 ```typescript
 import { defaultLogger } from '@push.rocks/smartlog';
 
-defaultLogger.log('info', 'Application started');
+defaultLogger.log('info', 'This is so easy!');
 ```
 
-### Log Groups
+## 📚 Core Concepts
 
-Group related logs for better traceability:
+### Log Levels
+
+smartlog supports semantic log levels for different scenarios:
 
 ```typescript
-// Create a log group with optional transaction ID
+// Lifecycle events
-const requestGroup = logger.createLogGroup('tx-123456');
+logger.log('lifecycle', '🔄 Container starting up...');
 
-// Logs within this group will be correlated
+// Success states
-requestGroup.log('info', 'Processing payment request');
+logger.log('success', '✅ Payment processed');
-requestGroup.log('debug', 'Validating payment details');
+logger.log('ok', '👍 Health check passed');
-requestGroup.log('success', 'Payment processed successfully');
+
+// Information and debugging
+logger.log('info', '📋 User profile updated');
+logger.log('note', '📌 Cache invalidated');
+logger.log('debug', '🔍 Query execution plan', { sql: 'SELECT * FROM users' });
+
+// Warnings and errors
+logger.log('warn', '⚠️  Memory usage above 80%');
+logger.log('error', '❌ Failed to send email');
+
+// Verbose output
+logger.log('silly', '🔬 Entering function processPayment()');
 ```
 
-### Custom Log Destinations
+### Log Groups for Correlation
 
-Extend logging capabilities by adding custom destinations:
+Perfect for tracking request flows through your system:
 
 ```typescript
-import { Smartlog, ILogDestination } from '@push.rocks/smartlog';
+// Track a user request through multiple operations
+const requestGroup = logger.createLogGroup('req-7f3a2b');
 
-class DatabaseLogDestination implements ILogDestination {
+requestGroup.log('info', 'Received POST /api/users');
-  async handleLog(logPackage) {
+requestGroup.log('debug', 'Validating request body');
-    // Store log in database
+requestGroup.log('info', 'Creating user in database');
-    await db.logs.insert({
+requestGroup.log('success', 'User created successfully', { userId: 'usr_123' });
-      timestamp: new Date(logPackage.timestamp),
+
+// All logs in the group share the same correlation ID
+```
+
+## 🎯 Log Destinations
+
+### Built-in Destinations
+
+#### 🖥️ Local Console (Enhanced)
+
+Beautiful, colored output for local development:
+
+```typescript
+import { DestinationLocal } from '@push.rocks/smartlog/destination-local';
+
+const localDestination = new DestinationLocal({
+  logLevel: 'debug'  // Optional: filter by minimum log level
+});
+
+logger.addLogDestination(localDestination);
+```
+
+#### 📁 File Logging
+
+Persist logs to files with automatic rotation support:
+
+```typescript
+import { SmartlogDestinationFile } from '@push.rocks/smartlog/destination-file';
+
+const fileDestination = new SmartlogDestinationFile('./logs/app.log');
+logger.addLogDestination(fileDestination);
+```
+
+#### 🌐 Browser DevTools
+
+Optimized for browser environments with styled console output:
+
+```typescript
+import { SmartlogDestinationDevtools } from '@push.rocks/smartlog/destination-devtools';
+
+const devtools = new SmartlogDestinationDevtools();
+logger.addLogDestination(devtools);
+```
+
+#### 📊 ClickHouse Analytics
+
+Store logs in ClickHouse for powerful analytics:
+
+```typescript
+import { SmartlogDestinationClickhouse } from '@push.rocks/smartlog/destination-clickhouse';
+
+const clickhouse = await SmartlogDestinationClickhouse.createAndStart({
+  host: 'analytics.example.com',
+  port: 8123,
+  database: 'logs',
+  user: 'logger',
+  password: process.env.CLICKHOUSE_PASSWORD
+});
+
+logger.addLogDestination(clickhouse);
+
+// Query your logs with SQL!
+// SELECT * FROM logs WHERE level = 'error' AND timestamp > now() - INTERVAL 1 HOUR
+```
+
+#### 🔗 Remote Receiver
+
+Send logs to a centralized logging service:
+
+```typescript
+import { SmartlogDestinationReceiver } from '@push.rocks/smartlog/destination-receiver';
+
+const receiver = new SmartlogDestinationReceiver({
+  endpoint: 'https://logs.mycompany.com/ingest',
+  apiKey: process.env.LOG_API_KEY,
+  batchSize: 100,  // Send logs in batches
+  flushInterval: 5000  // Flush every 5 seconds
+});
+
+logger.addLogDestination(receiver);
+```
+
+### 🛠️ Custom Destinations
+
+Build your own destination for any logging backend:
+
+```typescript
+import { ILogDestination, ILogPackage } from '@push.rocks/smartlog/interfaces';
+
+class ElasticsearchDestination implements ILogDestination {
+  private client: ElasticsearchClient;
+
+  constructor(config: ElasticsearchConfig) {
+    this.client = new ElasticsearchClient(config);
+  }
+
+  async handleLog(logPackage: ILogPackage): Promise<void> {
+    await this.client.index({
+      index: `logs-${new Date().toISOString().split('T')[0]}`,
+      body: {
+        '@timestamp': logPackage.timestamp,
         level: logPackage.level,
         message: logPackage.message,
+        context: logPackage.context,
         data: logPackage.data,
-      context: logPackage.context
+        correlation: logPackage.correlation
+      }
     });
   }
 }
 
-// Add the custom destination to your logger
+// Use your custom destination
-logger.addLogDestination(new DatabaseLogDestination());
+logger.addLogDestination(new ElasticsearchDestination({
-```
+  node: 'https://elasticsearch.example.com'
-
-### Built-in Destinations

-const clickhouse = await SmartlogDestinationClickhouse.createAndStart({
-  host: 'clickhouse.example.com',
-  port: 8123,
-  user: 'username',
-  password: 'password',
-  database: 'logs_db'
-});
-logger.addLogDestination(clickhouse);
-
-// Remote receiver logging
-import { SmartlogDestinationReceiver } from '@push.rocks/smartlog/destination-receiver';
-logger.addLogDestination(new SmartlogDestinationReceiver({
-  endpoint: 'https://logs.example.com/api/logs'
 }));
 ```
 
-### Interactive Console Features
+## 🎨 Interactive Console Features
 
-For CLI applications, use the interactive console features:
+### Spinners
+
+Create beautiful loading animations that degrade gracefully in CI/CD:
 
 ```typescript
-import { SmartlogSourceInteractive, SmartlogProgressBar } from '@push.rocks/smartlog/source-interactive';
+import { SmartlogSourceInteractive } from '@push.rocks/smartlog/source-interactive';
-```
 
-#### Spinners
-
-```typescript
 const spinner = new SmartlogSourceInteractive();
 
-// Start a spinner with text
+// Basic usage
-spinner.text('Loading data...');
+spinner.text('🔄 Fetching data from API...');
+// ... perform async operation
+spinner.finishSuccess('✅ Data fetched successfully!');
+
+// Chained operations
+spinner
+  .text('📡 Connecting to database')
+  .successAndNext('🔍 Running migrations')
+  .successAndNext('🌱 Seeding data')
+  .finishSuccess('🎉 Database ready!');
 
 // Customize appearance
-spinner.setSpinnerStyle('dots');  // 'dots', 'line', 'star', 'simple'
+spinner
-spinner.setColor('blue');         // 'red', 'green', 'yellow', 'blue', etc.
+  .setSpinnerStyle('dots')  // dots, line, star, simple
-spinner.setSpeed(80);             // Animation speed in milliseconds
+  .setColor('cyan')         // any terminal color
+  .setSpeed(80)            // animation speed in ms
+  .text('🚀 Deploying application...');
 
-// Update spinner status
+// Handle failures
-spinner.text('Processing records...');
+try {
-
+  await deployApp();
-// Complete with success or failure
+  spinner.finishSuccess('✅ Deployed!');
-spinner.finishSuccess('Data loaded successfully!');
+} catch (error) {
-spinner.finishFail('Failed to load data!');
+  spinner.finishFail('❌ Deployment failed');
-
+}
-// Chain operations
-spinner.text('Connecting to server')
-  .successAndNext('Fetching records')
-  .successAndNext('Processing data')
-  .finishSuccess('All done!');
 ```
 
-#### Progress Bars
+### Progress Bars
+
+Track long-running operations with style:
 
 ```typescript
-const progressBar = new SmartlogProgressBar({
+import { SmartlogProgressBar } from '@push.rocks/smartlog/source-interactive';
-  total: 100,                // Total number of items
+
-  width: 40,                 // Width of the progress bar
+// Create a progress bar
-  complete: '█',             // Character for completed section
+const progress = new SmartlogProgressBar({
-  incomplete: '░',           // Character for incomplete section
+  total: 100,
-  showEta: true,             // Show estimated time remaining
+  width: 40,
-  showPercent: true,         // Show percentage
+  complete: '█',
-  showCount: true            // Show count (e.g., "50/100")
+  incomplete: '░',
+  showEta: true,
+  showPercent: true,
+  showCount: true
 });
 
 // Update progress
-progressBar.update(25);      // Set to 25% progress
+for (let i = 0; i <= 100; i++) {
+  progress.update(i);
+  await someAsyncWork();
+}
 
-// Increment progress
+progress.complete();
-progressBar.increment(5);    // Increase by 5 units
 
-// Change color
+// Real-world example: Processing files
-progressBar.setColor('blue');
+const files = await getFiles();
+const progress = new SmartlogProgressBar({
+  total: files.length,
+  width: 50
+});
 
-// Complete the progress bar
+for (const [index, file] of files.entries()) {
-progressBar.complete();
+  await processFile(file);
+  progress.increment();  // or progress.update(index + 1)
+}
 ```
 
-#### Non-Interactive Environments
+### Non-Interactive Fallback
 
-Both spinners and progress bars automatically detect non-interactive environments (CI/CD, piped output) and fallback to plain text logging:
+Both spinners and progress bars automatically detect non-interactive environments (CI/CD, Docker logs, piped output) and fallback to simple text output:
 
 ```
-[Loading] Connecting to server
+[Loading] Connecting to database
-[Success] Connected to server
+[Success] Connected to database
-[Loading] Fetching records
+[Loading] Running migrations
+Progress: 25% (25/100)
 Progress: 50% (50/100)
 Progress: 100% (100/100)
-[Success] Fetching complete
+[Success] Migrations complete
 ```
 
-## Advanced Usage
+## 🔧 Advanced Features
 
-### Capturing All Console Output
+### Context Management
 
-Capture all `console.log` and `console.error` output through Smartlog:
+Add context that flows through your entire application:
 
 ```typescript
-logger.enableConsole({ captureAll: true });
+// Set global context
+logger.addLogContext({
+  requestId: 'req-123',
+  userId: 'user-456',
+  feature: 'payment-processing'
+});
+
+// All subsequent logs include this context
+logger.log('info', 'Processing payment');
+// Output includes: { ...context, message: 'Processing payment' }
+```
+
+### Scoped Logging
+
+Create scoped loggers for different components:
+
+```typescript
+const dbLogger = logger.createScope('database');
+const apiLogger = logger.createScope('api');
+
+dbLogger.log('info', 'Executing query');
+apiLogger.log('info', 'Handling request');
+// Logs include scope information for filtering
+```
+
+### Minimum Log Levels
+
+Control log verbosity per environment:
+
+```typescript
+const logger = new Smartlog({
+  logContext: { environment: 'production' },
+  minimumLogLevel: 'warn'  // Only warn and above in production
+});
+
+// These won't be logged in production
+logger.log('debug', 'Detailed debug info');
+logger.log('info', 'Regular info');
+
+// These will be logged
+logger.log('warn', 'Warning message');
+logger.log('error', 'Error message');
 ```
 
 ### Increment Logging
 
-For metrics and counters:
+Perfect for metrics and counters:
 
 ```typescript
-logger.increment('info', 'api_requests', { endpoint: '/users' });
+// Track API calls
+logger.increment('info', 'api.requests', { endpoint: '/users', method: 'GET' });
+logger.increment('info', 'api.requests', { endpoint: '/users', method: 'POST' });
+
+// Track errors by type
+logger.increment('error', 'payment.failed', { reason: 'insufficient_funds' });
+logger.increment('error', 'payment.failed', { reason: 'card_declined' });
 ```
 
-### Log Correlation
+### Capture All Console Output
 
-Correlate logs across services with correlation IDs:
+Redirect all console.log and console.error through smartlog:
 
 ```typescript
-logger.log('info', 'Request received', { userId: 'user-123' }, {
+logger.enableConsole({ 
-  id: 'req-abc-123',
+  captureAll: true  // Capture all console.* methods
-  type: 'service',
+});
-  transaction: 'tx-payment-456'
+
+console.log('This goes through smartlog!');
+console.error('This too!');
+// All console output is now structured and routed through your destinations
+```
+
+## 🏗️ Real-World Examples
+
+### Microservice with Distributed Tracing
+
+```typescript
+import { Smartlog } from '@push.rocks/smartlog';
+import { SmartlogDestinationClickhouse } from '@push.rocks/smartlog/destination-clickhouse';
+
+// Initialize logger with service context
+const logger = new Smartlog({
+  logContext: {
+    company: 'TechCorp',
+    companyunit: 'Platform',
+    containerName: 'user-service',
+    environment: process.env.NODE_ENV,
+    runtime: 'node',
+    zone: process.env.CLOUD_ZONE
+  }
+});
+
+// Add ClickHouse for analytics
+const clickhouse = await SmartlogDestinationClickhouse.createAndStart({
+  host: process.env.CLICKHOUSE_HOST,
+  database: 'microservices_logs'
+});
+logger.addLogDestination(clickhouse);
+
+// Enable local console for development
+if (process.env.NODE_ENV === 'development') {
+  logger.enableConsole();
+}
+
+// Express middleware for request tracking
+app.use((req, res, next) => {
+  const requestId = generateRequestId();
+  const logGroup = logger.createLogGroup(requestId);
+  
+  // Attach logger to request
+  req.logger = logGroup;
+  
+  // Log request
+  logGroup.log('info', 'Incoming request', {
+    method: req.method,
+    path: req.path,
+    ip: req.ip
+  });
+  
+  // Track response
+  res.on('finish', () => {
+    logGroup.log('info', 'Request completed', {
+      statusCode: res.statusCode,
+      duration: Date.now() - req.startTime
+    });
+  });
+  
+  next();
 });

+        channel: 'ops-team',
+        message: `🚨 Critical error: ${logPackage.message}`,
+        data: logPackage
+      });
+    }
+  }
+});

+
+## 🔌 Integration with Other Tools
+
+### PM2 Integration
+
+```typescript
+// ecosystem.config.js
+module.exports = {
+  apps: [{
+    name: 'api',
+    script: './dist/index.js',
+    error_file: '/dev/null',  // Disable PM2 error log
+    out_file: '/dev/null',    // Disable PM2 out log
+    merge_logs: true,
+    env: {
+      NODE_ENV: 'production',
+      // smartlog handles all logging
+    }
+  }]
+};
+```
+
+### Docker Integration
+
+```dockerfile
+FROM node:18-alpine
+WORKDIR /app
+COPY . .
+RUN pnpm install --production
+
+# smartlog handles structured logging
+# No need for special log drivers
+CMD ["node", "dist/index.js"]
+```
+
+```yaml
+# docker-compose.yml
+services:
+  app:
+    build: .
+    environment:
+      - NODE_ENV=production
+    # Logs are structured JSON, perfect for log aggregators
+    logging:
+      driver: "json-file"
+      options:
+        max-size: "10m"
+        max-file: "3"
+```
+
+## 🏆 Best Practices
+
+### 1. Use Semantic Log Levels
+
+```typescript
+// ✅ Good - semantic and meaningful
+logger.log('lifecycle', 'Server starting on port 3000');
+logger.log('success', 'Database connection established');
+logger.log('error', 'Failed to process payment', { orderId, error });
+
+// ❌ Bad - everything is 'info'
+logger.log('info', 'Server starting');
+logger.log('info', 'Database connected');
+logger.log('info', 'Error: payment failed');
+```
+
+### 2. Include Structured Data
+
+```typescript
+// ✅ Good - structured data for analysis
+logger.log('error', 'API request failed', {
+  endpoint: '/api/users',
+  statusCode: 500,
+  duration: 1234,
+  userId: 'usr_123',
+  errorCode: 'INTERNAL_ERROR'
+});
+
+// ❌ Bad - data embedded in message
+logger.log('error', `API request to /api/users failed with 500 in 1234ms for user usr_123`);
+```
+
+### 3. Use Log Groups for Correlation
+
+```typescript
+// ✅ Good - correlated logs
+async function processOrder(orderId: string) {
+  const logGroup = logger.createLogGroup(orderId);
+  
+  logGroup.log('info', 'Processing order');
+  logGroup.log('debug', 'Validating items');
+  logGroup.log('info', 'Charging payment');
+  logGroup.log('success', 'Order processed');
+}
+
+// ❌ Bad - no correlation
+async function processOrder(orderId: string) {
+  logger.log('info', `Processing order ${orderId}`);
+  logger.log('debug', `Validating items for ${orderId}`);
+  logger.log('info', `Charging payment for ${orderId}`);
+}
+```
+
+### 4. Environment-Specific Configuration
+
+```typescript
+// ✅ Good - different configs per environment
+const logger = new Smartlog({
+  logContext: {
+    environment: process.env.NODE_ENV,
+    // ... other context
+  },
+  minimumLogLevel: process.env.NODE_ENV === 'production' ? 'info' : 'silly'
+});
+
+// Add destinations based on environment
+if (process.env.NODE_ENV === 'production') {
+  logger.addLogDestination(clickhouseDestination);
+  logger.addLogDestination(alertingDestination);
+} else {
+  logger.enableConsole();
+}
+```
+
+## 📖 API Reference
+
+### Smartlog Class
+
+```typescript
+class Smartlog {
+  constructor(options?: ISmartlogOptions)
+  
+  // Logging methods
+  log(level: TLogLevel, message: string, data?: any, correlation?: ILogCorrelation): void
+  increment(level: TLogLevel, key: string, data?: any): void
+  
+  // Configuration
+  enableConsole(options?: IConsoleOptions): void
+  addLogDestination(destination: ILogDestination): void
+  addLogContext(context: Partial<ILogContext>): void
+  
+  // Log groups
+  createLogGroup(transactionId?: string): LogGroup
+  createScope(scopeName: string): Smartlog
+}
+```
+
+### Log Levels
+
+```typescript
+type TLogLevel = 
+  | 'silly'      // Very verbose debugging
+  | 'debug'      // Debug information
+  | 'info'       // Informational messages
+  | 'note'       // Notable events
+  | 'ok'         // Success confirmation
+  | 'success'    // Major success
+  | 'warn'       // Warning messages
+  | 'error'      // Error messages
+  | 'lifecycle'  // Application lifecycle events
+```
+
+### Log Package Structure
+
+```typescript
+interface ILogPackage {
+  timestamp: number;
+  level: TLogLevel;
+  message: string;
+  data?: any;
+  context: ILogContext;
+  correlation?: ILogCorrelation;
+}
+```
