+# Sentry CocoaLumberjack Integration
+
+A [CocoaLumberjack](https://github.com/CocoaLumberjack/CocoaLumberjack) logger that forwards log entries to Sentry's structured logging system, automatically capturing application logs with full context including source location, thread information, and log levels.
+
+> [!NOTE]
+> This repo is a mirror of [github.com/getsentry/sentry-cocoa](https://github.com/getsentry/sentry-cocoa). The source code lives in `3rd-party-integrations/SentryCocoaLumberjack/`. This allows users to import only what they need via SPM while keeping all integration code in the main repository.
+
+## Installation
+
+### Swift Package Manager
+
+Add the following dependencies to your `Package.swift` or Xcode package dependencies:
+
+```swift
+dependencies: [
+    .package(url: "https://github.com/getsentry/sentry-cocoa-cocoalumberjack", from: "1.0.0")
+]
+```
+
+## Quick Start
+
+```swift
+import Sentry
+import SentryCocoaLumberjack
+import CocoaLumberjackSwift
+
+SentrySDK.start { options in
+    options.dsn = "YOUR_DSN"
+    options.enableLogs = true
+}
+
+DDLog.add(SentryCocoaLumberjackLogger())
+
+DDLogInfo("User logged in")
+DDLogError("Payment failed")
+DDLogWarn("API rate limit approaching")
+DDLogDebug("Processing request")
+DDLogVerbose("Detailed trace information")
+```
+
+## Configuration
+
+### Log Level Threshold
+
+Set the minimum log level for messages to be sent to Sentry:
+
+```swift
+DDLog.add(SentryCocoaLumberjackLogger(logLevel: .verbose))
+```
+
+Messages below the configured threshold will be filtered out and not sent to Sentry.
+
+## Log Level Mapping
+
+CocoaLumberjack log levels are automatically mapped to Sentry log levels:
+
+| CocoaLumberjack Level | Sentry Log Level |
+| --------------------- | ---------------- |
+| `.error`              | `.error`         |
+| `.warning`            | `.warn`          |
+| `.info`               | `.info`          |
+| `.debug`              | `.debug`         |
+| `.verbose`            | `.trace`         |
+
+## Automatic Attributes
+
+The logger automatically includes the following attributes with every log entry:
+
+- `sentry.origin`: `"auto.logging.cocoalumberjack"`
+- `cocoalumberjack.level`: The original CocoaLumberjack log level (error, warning, info, debug, verbose)
+- `cocoalumberjack.file`: The source file name
+- `cocoalumberjack.function`: The function name
+- `cocoalumberjack.line`: The line number
+- `cocoalumberjack.context`: The log context (integer)
+- `cocoalumberjack.timestamp`: The log timestamp
+- `cocoalumberjack.threadID`: The thread ID
+- `cocoalumberjack.threadName`: The thread name (if available)
+- `cocoalumberjack.queueLabel`: The dispatch queue label (if available)
+
+## Documentation
+
+- [Sentry Cocoa SDK Documentation](https://docs.sentry.io/platforms/apple/)
+- [Sentry Logs Documentation](https://docs.sentry.io/platforms/apple/logs/)
+- [CocoaLumberjack Repo](https://github.com/CocoaLumberjack/CocoaLumberjack)

+import CocoaLumberjackSwift
+import Sentry
+
+/// A CocoaLumberjack logger that forwards log entries to Sentry's structured logging system.
+///
+/// `SentryCocoaLumberjackLogger` implements CocoaLumberjack's `DDAbstractLogger` protocol, allowing you
+/// to integrate Sentry's structured logging capabilities with CocoaLumberjack. This enables you to capture
+/// application logs from CocoaLumberjack and send them to Sentry for analysis and monitoring.
+///
+/// ## Level Filtering
+/// The logger supports filtering by log level. Only logs at or above the configured `logLevel` will be
+/// sent to Sentry. Defaults to `.info`.
+///
+/// ## Level Mapping
+/// CocoaLumberjack log levels are mapped to Sentry log levels:
+/// - `.error` → `.error`
+/// - `.warning` → `.warn`
+/// - `.info` → `.info`
+/// - `.debug` → `.debug`
+/// - `.verbose` → `.trace`
+///
+/// ## Usage
+/// ```swift
+/// import CocoaLumberjackSwift
+/// import Sentry
+/// import SentryCocoaLumberjack
+///
+/// // Initialize Sentry SDK
+/// SentrySDK.start { options in
+///     options.dsn = "YOUR_DSN"
+/// }
+///
+/// // Add SentryCocoaLumberjackLogger to CocoaLumberjack
+/// // Only logs at .info level and above will be sent to Sentry
+/// DDLog.add(SentryCocoaLumberjackLogger(logLevel: .info))
+///
+/// // Use CocoaLumberjack as usual
+/// DDLogInfo("User logged in")
+/// DDLogError("Payment failed")
+/// ```
+///
+/// - Note: Sentry Logs is currently in Beta. See the [Sentry Logs Documentation](https://docs.sentry.io/platforms/apple/logs/).
+/// - Warning: This logger requires Sentry SDK to be initialized before use.
