+# Sentry SwiftLog Integration
+
+A [SwiftLog](https://github.com/apple/swift-log) handler that forwards log entries to Sentry's structured logging system, automatically capturing application logs with full context including metadata, source location, 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/SentrySwiftLog/`. 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-swiftlog", from: "1.0.0")
+]
+```
+
+## Quick Start
+
+```swift
+import Sentry
+import Logging
+
+SentrySDK.start { options in
+    options.dsn = "YOUR_DSN"
+    options.enableLogs = true
+}
+
+var handler = SentryLogHandler(logLevel: .info)
+handler.metadata["app_version"] = "1.0.0"
+handler.metadata["environment"] = "production"
+
+LoggingSystem.bootstrap { _ in handler }
+
+let logger = Logger(label: "com.example.app")
+
+logger.info("User logged in", metadata: ["userId": "12345"])
+logger.error("Payment failed", metadata: ["errorCode": 500])
+logger.warning("API rate limit approaching", metadata: ["remaining": 10])
+
+logger.info("User action", metadata: [
+    "userId": "12345",
+    "action": "purchase"
+])
+```
+
+## Configuration
+
+### Log Level Threshold
+
+Set the minimum log level for messages to be sent to Sentry. Messages below the configured threshold will be filtered out and not sent to Sentry.
+
+```swift
+let handler = SentryLogHandler(logLevel: .trace)
+```
+
+### Handler Metadata
+
+Add metadata that will be included with all log entries. Handler metadata is merged with call-site metadata, with call-site metadata taking precedence.
+
+```swift
+var handler = SentryLogHandler(logLevel: .info)
+handler.metadata["app_version"] = "1.0.0"
+handler.metadata["environment"] = "production"
+```
+
+You can also access metadata using subscript syntax:
+
+```swift
+handler[metadataKey: "app_version"] = "1.0.0"
+let version = handler[metadataKey: "app_version"]
+```
+
+## Log Level Mapping
+
+`swift-log` levels are automatically mapped to Sentry log levels:
+
+| swift-log Level | Sentry Log Level |
+| --------------- | ---------------- |
+| `.trace`        | `.trace`         |
+| `.debug`        | `.debug`         |
+| `.info`         | `.info`          |
+| `.notice`       | `.info`          |
+| `.warning`      | `.warn`          |
+| `.error`        | `.error`         |
+| `.critical`     | `.fatal`         |
+
+## Metadata Handling
+
+The handler supports all `swift-log` metadata types including strings, dictionaries, arrays, and string convertible types (numbers, booleans, etc.). All metadata is automatically prefixed with `swift-log.` in Sentry attributes (e.g., `swift-log.userId`, `swift-log.user.id`). See the Quick Start section above for examples of each metadata type.
+
+## Automatic Attributes
+
+The handler automatically includes the following attributes with every log entry:
+
+- `sentry.origin`: `"auto.logging.swift-log"`
+- `swift-log.level`: The original swift-log level
+- `swift-log.source`: The log source
+- `swift-log.file`: The source file name
+- `swift-log.function`: The function name
+- `swift-log.line`: The line number
+
