+# Error Tracking
+
+This package provides error tracking integration for ResolveSpec, with built-in support for Sentry.
+
+## Features
+
+- **Provider Interface**: Flexible design supporting multiple error tracking backends
+- **Sentry Integration**: Full-featured Sentry support with automatic error, warning, and panic tracking
+- **Automatic Logger Integration**: All `logger.Error()` and `logger.Warn()` calls are automatically sent to the error tracker
+- **Panic Tracking**: Automatic panic capture with stack traces
+- **NoOp Provider**: Zero-overhead when error tracking is disabled
+
+## Configuration
+
+Add error tracking configuration to your config file:
+
+```yaml
+error_tracking:
+  enabled: true
+  provider: "sentry"  # Currently supports: "sentry" or "noop"
+  dsn: "https://your-sentry-dsn@sentry.io/project-id"
+  environment: "production"  # e.g., production, staging, development
+  release: "v1.0.0"  # Your application version
+  debug: false
+  sample_rate: 1.0  # Error sample rate (0.0-1.0)
+  traces_sample_rate: 0.1  # Traces sample rate (0.0-1.0)
+```
+
+## Usage
+
+### Initialization
+
+Initialize error tracking in your application startup:
+
+```go
+package main
+
+import (
+    "github.com/bitechdev/ResolveSpec/pkg/config"
+    "github.com/bitechdev/ResolveSpec/pkg/errortracking"
+    "github.com/bitechdev/ResolveSpec/pkg/logger"
+)
+
+func main() {
+    // Load your configuration
+    cfg := config.Config{
+        ErrorTracking: config.ErrorTrackingConfig{
+            Enabled:     true,
+            Provider:    "sentry",
+            DSN:         "https://your-sentry-dsn@sentry.io/project-id",
+            Environment: "production",
+            Release:     "v1.0.0",
+            SampleRate:  1.0,
+        },
+    }
+
+    // Initialize logger
+    logger.Init(false)
+
+    // Initialize error tracking
+    provider, err := errortracking.NewProviderFromConfig(cfg.ErrorTracking)
+    if err != nil {
+        logger.Error("Failed to initialize error tracking: %v", err)
+    } else {
+        logger.InitErrorTracking(provider)
+    }
+
+    // Your application code...
+
+    // Cleanup on shutdown
+    defer logger.CloseErrorTracking()
+}
+```
+
+### Automatic Tracking
+
+Once initialized, all logger errors and warnings are automatically sent to the error tracker:
+
+```go
+// This will be logged AND sent to Sentry
+logger.Error("Database connection failed: %v", err)
+
+// This will also be logged AND sent to Sentry
+logger.Warn("Cache miss for key: %s", key)
+```
+
+### Panic Tracking
+
+Panics are automatically captured when using the logger's panic handlers:
+
+```go
+// Using CatchPanic
+defer logger.CatchPanic("MyFunction")
+
+// Using CatchPanicCallback
+defer logger.CatchPanicCallback("MyFunction", func(err any) {
+    // Custom cleanup
+})
+
+// Using HandlePanic
+defer func() {
+    if r := recover(); r != nil {
+        err = logger.HandlePanic("MyMethod", r)
+    }
+}()
+```
+
+### Manual Tracking
+
+You can also use the provider directly for custom error tracking:
+
+```go
+import (
+    "context"
+    "github.com/bitechdev/ResolveSpec/pkg/errortracking"
+    "github.com/bitechdev/ResolveSpec/pkg/logger"
+)
+
+func someFunction() {
+    tracker := logger.GetErrorTracker()
+    if tracker != nil {
+        // Capture an error
+        tracker.CaptureError(context.Background(), err, errortracking.SeverityError, map[string]interface{}{
+            "user_id": userID,
+            "request_id": requestID,
+        })
+
+        // Capture a message
+        tracker.CaptureMessage(context.Background(), "Important event occurred", errortracking.SeverityInfo, map[string]interface{}{
+            "event_type": "user_signup",
+        })
+
+        // Capture a panic
+        tracker.CapturePanic(context.Background(), recovered, stackTrace, map[string]interface{}{
+            "context": "background_job",
+        })
+    }
+}
+```
+
+## Severity Levels
+
+The package supports the following severity levels:
+
+- `SeverityError`: For errors that should be tracked and investigated
+- `SeverityWarning`: For warnings that may indicate potential issues
+- `SeverityInfo`: For informational messages
+- `SeverityDebug`: For debug-level information
+
+```
