+## ✨ 核心特性
+
+![Langfuse 概览](https://langfuse.com/images/docs/github-readme/github-feature-overview.png)
+
+- [LLM 应用可观察性](https://langfuse.com/docs/tracing)：为你的应用插入仪表代码，并开始将追踪数据传送到 Langfuse，从而追踪 LLM 调用及应用中其他相关逻辑（如检索、嵌入或代理操作）。检查并调试复杂日志及用户会话。试试互动的 [演示](https://langfuse.com/docs/demo) 看看效果。
+  
+- [提示管理](https://langfuse.com/docs/prompts/get-started) 帮助你集中管理、版本控制并协作迭代提示。得益于服务器和客户端的高效缓存，你可以在不增加延迟的情况下反复迭代提示。
+
+- [评估](https://langfuse.com/docs/scores/overview) 是 LLM 应用开发流程的关键组成部分，Langfuse 能够满足你的多样需求。它支持 LLM 作为“裁判”、用户反馈收集、手动标注以及通过 API/SDK 实现自定义评估流程。
+
+- [数据集](https://langfuse.com/docs/datasets/overview) 为评估你的 LLM 应用提供测试集和基准。它们支持持续改进、部署前测试、结构化实验、灵活评估，并能与 LangChain、LlamaIndex 等框架无缝整合。
+
+- [LLM 试玩平台](https://langfuse.com/docs/playground) 是用于测试和迭代提示及模型配置的工具，缩短反馈周期，加速开发。当你在追踪中发现异常结果时，可以直接跳转至试玩平台进行调整。
+
+- [综合 API](https://langfuse.com/docs/api)：Langfuse 常用于驱动定制化的 LLMOps 工作流程，同时利用 Langfuse 提供的构建模块和 API。我们提供 OpenAPI 规格、Postman 集合以及针对 Python 和 JS/TS 的类型化 SDK。

+
+## 🚀 快速入门
+
+为你的应用增加仪表代码，并开始将追踪数据上传到 Langfuse，从而记录 LLM 调用及应用中其他相关逻辑（如检索、嵌入或代理操作）。
+
+### 1️⃣ 创建新项目
+
+1. [创建 Langfuse 账户](https://cloud.langfuse.com/auth/sign-up) 或 [自托管](https://langfuse.com/self-hosting)
+2. 创建一个新项目
+3. 在项目设置中创建新的 API 凭证
+
+### 2️⃣ 记录你的第一个 LLM 调用
+
+使用 [<code>@observe()</code> 装饰器](https://langfuse.com/docs/sdk/python/decorators) 可轻松跟踪任何 Python LLM 应用。在本快速入门中，我们还使用了 Langfuse 的 [OpenAI 集成](https://langfuse.com/docs/integrations/openai) 来自动捕获所有模型参数。
+
+> [!提示]
+> 不使用 OpenAI？请访问 [我们的文档](https://langfuse.com/docs/get-started#log-your-first-llm-call-to-langfuse) 了解如何记录其他模型和框架。
+
+安装依赖：
+
+````bash
+pip install langfuse openai
+````
+
+配置环境变量（创建名为 **.env** 的文件）：
+
+````bash:.env
+LANGFUSE_SECRET_KEY="sk-lf-..."
+LANGFUSE_PUBLIC_KEY="pk-lf-..."
+LANGFUSE_HOST="https://cloud.langfuse.com" # 🇪🇺 欧盟区域
+# LANGFUSE_HOST="https://us.cloud.langfuse.com" # 🇺🇸 美洲区域
+````
+
+创建示例代码（文件名：**main.py**）：
+
+````python:main.py
+from langfuse.decorators import observe
+from langfuse.openai import openai  # OpenAI 集成
+
+@observe()
+def story():
+    return openai.chat.completions.create(
+        model="gpt-4o",
+        messages=[{"role": "user", "content": "What is Langfuse?"}],
+    ).choices[0].message.content
+
+@observe()
+def main():
+    return story()
+
+main()
+````
+
+### 3️⃣ 在 Langfuse 中查看追踪记录
+
+在 Langfuse 中查看你的语言模型调用及其他应用逻辑。

+
+![Langfuse Overview](https://langfuse.com/images/docs/github-readme/github-feature-overview.png)
+
+- **[LLMアプリケーションの可観測性](https://langfuse.com/docs/tracing):**  
+  アプリケーションにインストゥルメンテーションを導入し、Langfuseへトレースを取り込むことで、LLM呼び出しやリトリーバル、埋め込み、エージェントアクションなどの関連ロジックを追跡できます。  
+  複雑なログやユーザーセッションを解析・デバッグできます。  
+  インタラクティブな[デモ](https://langfuse.com/docs/demo)で動作を確認してください。
+
+- **[プロンプト管理](https://langfuse.com/docs/prompts/get-started):**  
+  プロンプトを一元管理し、バージョン管理しながら共同で改善を行えます。  
+  サーバーおよびクライアント側で強力なキャッシングを行うため、アプリケーションのレイテンシを増やすことなくプロンプトの改良が可能です。
+
+- **[評価](https://langfuse.com/docs/scores/overview):**  
+  評価はLLMアプリケーション開発ワークフローの要であり、Langfuseは多様なニーズに対応します。

+## 🚀 クイックスタート
+
+アプリケーションにインストゥルメンテーションを導入し、LLM呼び出しやリトリーバル、埋め込み、エージェントアクションなどの動作をLangfuseに記録しましょう。  
+複雑なログやユーザーセッションの解析・デバッグが可能になります。
+
+### 1️⃣ 新規プロジェクトの作成
+
+1. [Langfuseアカウント作成](https://cloud.langfuse.com/auth/sign-up) または [セルフホスト](https://langfuse.com/self-hosting)
+2. 新規プロジェクトを作成
+3. プロジェクト設定で新しいAPIクレデンシャルを作成
+
+### 2️⃣ 初めてのLLM呼び出しのログ記録
+
+[`@observe()` デコレーター](https://langfuse.com/docs/sdk/python/decorators)を利用することで、任意のPython製LLMアプリケーションのトレースが簡単に行えます。  
+このクイックスタートでは、Langfuseの[OpenAI統合](https://langfuse.com/docs/integrations/openai)を使用して、全てのモデルパラメータを自動で取得します。
+
+> [!TIP]
+> OpenAIを利用していない場合は、[こちらのドキュメント](https://langfuse.com/docs/get-started#log-your-first-llm-call-to-langfuse)で、他のモデルやフレームワークのログ記録方法をご確認ください。
+
+```bash
+pip install langfuse openai
+```
+
+```bash filename=".env"
+LANGFUSE_SECRET_KEY="sk-lf-..."
+LANGFUSE_PUBLIC_KEY="pk-lf-..."
+LANGFUSE_HOST="https://cloud.langfuse.com" # 🇪🇺 EUリージョン
+# LANGFUSE_HOST="https://us.cloud.langfuse.com" # 🇺🇸 USリージョン
+```
+
+```python:/@observe()/ /from langfuse.openai import openai/ filename="main.py"
+from langfuse.decorators import observe
+from langfuse.openai import openai  # OpenAI統合
+
+@observe()
+def story():
+    return openai.chat.completions.create(
+        model="gpt-4o",
+        messages=[{"role": "user", "content": "What is Langfuse?"}],
+    ).choices[0].message.content
+
+@observe()
+def main():
+    return story()
+
+main()
+```
+
+### 3️⃣ Langfuseでトレースを確認する
+
+Langfuse上で、LLM呼び出しおよびその他のアプリケーションロジックのトレースを確認できます。

+
+## ✨ 주요 기능
+
+![Langfuse Overview](https://langfuse.com/images/docs/github-readme/github-feature-overview.png)
+
+- **LLM 애플리케이션 관측**  
+  앱에 계측(instrumentation)을 추가하여 Langfuse로 trace 데이터를 수집함으로써, 검색, 임베딩, 또는 에이전트 동작과 같은 LLM 호출 및 기타 관련 로직을 추적할 수 있습니다. 복잡한 로그와 사용자 세션을 확인 및 디버깅 해보세요. 인터랙티브 데모를 통해 실제 작동 예를 확인할 수 있습니다.
+
+- **프롬프트 관리**  
+  프롬프트를 중앙에서 관리하고 버전 관리하며 협업으로 수정할 수 있도록 도와줍니다. 서버와 클라이언트 측의 강력한 캐싱 덕분에 애플리케이션에 지연(latency)을 추가하지 않고도 프롬프트를 반복 개선할 수 있습니다.
+
+- **평가**  
+  LLM 애플리케이션 개발 워크플로우에서 핵심적인 역할을 하며, Langfuse는 여러분의 필요에 맞게 유연하게 대응합니다. LLM을 심사자로 활용하는 기능, 사용자 피드백 수집, 수동 라벨링 및 API/SDK를 통한 맞춤 평가 파이프라인을 지원합니다.
+
+- **데이터셋**  
+  LLM 애플리케이션 평가를 위한 테스트 세트와 벤치마크를 제공하여, 지속적인 개선, 배포 전 테스트, 구조화된 실험, 유연한 평가 및 LangChain과 LlamaIndex와 같은 프레임워크와의 원활한 통합을 지원합니다.
+
+- **LLM 플레이그라운드**  
+  프롬프트와 모델 구성에 대해 테스트 및 반복 개선할 수 있는 도구로, 피드백 루프를 단축하여 개발 속도를 높여줍니다. trace에서 이상한 결과가 발생하면 플레이그라운드로 바로 이동해 개선할 수 있습니다.
+
+- **종합 API**  
+  Langfuse는 API를 통해 제공되는 구성 요소들을 활용하여 맞춤형 LLMOps 워크플로우를 강화하는 데 자주 사용됩니다. OpenAPI 명세, Postman 컬렉션, Python 및 JS/TS용 타입드 SDK가 제공됩니다.

+
+## 🚀 빠른 시작
+
+앱에 계측을 추가하고 Langfuse에 trace 데이터를 수집하여, LLM 호출 및 검색, 임베딩, 에이전트 동작과 같은 애플리케이션 로직을 추적해보세요. 복잡한 로그와 사용자 세션을 확인하여 디버깅할 수 있습니다.
+
+### 1️⃣ 새 프로젝트 생성
+
+1. [Langfuse 계정 생성](https://cloud.langfuse.com/auth/sign-up) 또는 [셀프 호스트](https://langfuse.com/self-hosting)
+2. 새 프로젝트를 생성합니다.
+3. 프로젝트 설정에서 새로운 API 자격 증명을 생성합니다.
+
+### 2️⃣ 첫 번째 LLM 호출 기록하기
+
+[`@observe()` 데코레이터](https://langfuse.com/docs/sdk/python/decorators)를 사용하면 Python LLM 애플리케이션의 추적이 매우 간편해집니다. 이 빠른 시작 예제에서는 Langfuse [OpenAI 통합](https://langfuse.com/docs/integrations/openai)을 사용하여 모든 모델 파라미터를 자동으로 캡처합니다.
+
+> [!TIP]
+> OpenAI를 사용하지 않으시다면, 다른 모델 및 프레임워크의 로그 기록 방법은 [문서](https://langfuse.com/docs/get-started#log-your-first-llm-call-to-langfuse)를 참조하세요.
+
+```bash
+pip install langfuse openai
+```
+
+```bash filename=".env"
+LANGFUSE_SECRET_KEY="sk-lf-..."
+LANGFUSE_PUBLIC_KEY="pk-lf-..."
+LANGFUSE_HOST="https://cloud.langfuse.com" # 🇪🇺 EU region
+# LANGFUSE_HOST="https://us.cloud.langfuse.com" # 🇺🇸 US region
+```
+
+```python:main.py
+from langfuse.decorators import observe
+from langfuse.openai import openai # OpenAI integration
+
+@observe()
+def story():
+    return openai.chat.completions.create(
+        model="gpt-4o",
+        messages=[{"role": "user", "content": "What is Langfuse?"}],
+    ).choices[0].message.content
+
+@observe()
+def main():
+    return story()
+
+main()
+```
+
+### 3️⃣ Langfuse에서 trace 확인하기
+
+Langfuse에서 LLM 호출 및 애플리케이션의 기타 로직에 대한 trace를 확인할 수 있습니다.
+

+## 🔒 보안 & 개인정보 보호
+
+우리는 데이터 보안과 개인정보 보호를 매우 중요하게 생각합니다. 자세한 내용은 [Security and Privacy](https://langfuse.com/security) 페이지를 참조하세요.
+
+### 텔레메트리
+
+기본적으로 Langfuse는 자체 호스팅 인스턴스의 기본 사용 통계를 중앙 서버(PostHog)로 자동 보고합니다.
+
+이를 통해:
+1. Langfuse가 어떻게 사용되는지 이해하고, 가장 관련성 높은 기능을 개선할 수 있습니다.
+2. 내부 및 외부(예: 자금 조달) 보고를 위한 전체 사용량을 추적할 수 있습니다.
+
+수집된 데이터는 제3자와 공유되지 않으며 민감한 정보를 포함하지 않습니다. 이에 대해 매우 투명하게 공개하고 있으며, 수집되는 정확한 데이터는 [여기](/web/src/features/telemetry/index.ts)에서 확인할 수 있습니다.
+
+환경 변수 `TELEMETRY_ENABLED=false`를 설정하여 옵트아웃할 수 있습니다.

+- [LLM Application Observability](https://langfuse.com/docs/tracing): Instrument your app and start ingesting traces to Langfuse, thereby tracking LLM calls and other relevant logic in your app such as retrieval, embedding, or agent actions. Inspect and debug complex logs and user sessions. Try the interactive [demo](https://langfuse.com/docs/demo) to see this in action.
 
-### Test
+- [Prompt Management](https://langfuse.com/docs/prompts/get-started) helps you centrally manage, version control, and collaboratively iterate on your prompts. Thanks to strong caching on server and client side, you can iterate on prompts without adding latency to your application.
 
-- **Experiments:** Track and test app behaviour before deploying a new version
-  - Datasets let you test expected in and output pairs and benchmark performance before deploying ([Datasets](https://langfuse.com/docs/datasets))
-  - Track versions and releases in your application ([Experimentation](https://langfuse.com/docs/experimentation), [Prompt Management](https://langfuse.com/docs/prompts))
+- [Evaluations](https://langfuse.com/docs/scores/overview) are key to the LLM application development workflow, and Langfuse adapts to your needs. It supports LLM-as-a-judge, user feedback collection, manual labeling, and custom evaluation pipelines via APIs/SDKs.
 
-## Get started
+- [Datasets](https://langfuse.com/docs/datasets/overview) enable test sets and benchmarks for evaluating your LLM application. They support continuous improvement, pre-deployment testing, structured experiments, flexible evaluation, and seamless integration with frameworks like LangChain and LlamaIndex.
+
+- [LLM Playground](https://langfuse.com/docs/playground) is a tool for testing and iterating on your prompts and model configurations, shortening the feedback loop and accelerating development. When you see a bad result in tracing, you can directly jump to the playground to iterate on it.
+
+- [Comprehensive API](https://langfuse.com/docs/api): Langfuse is frequently used to power bespoke LLMOps workflows while using the building blocks provided by Langfuse via the API. OpenAPI spec, Postman collection, and typed SDKs for Python, JS/TS are available.

+        Batched ingestion for Langfuse Tracing.
+        If you want to use tracing via the API, such as to build your own Langfuse client implementation, this is the only API route you need to implement.
+
+        Within each batch, there can be multiple events.
+        Each event has a type, an id, a timestamp, metadata and a body.
+        Internally, we refer to this as the "event envelope" as it tells us something about the event but not the trace.
+        We use the event id within this envelope to deduplicate messages to avoid processing the same event twice, i.e. the event id should be unique per request.
+        The event.body.id is the ID of the actual trace and will be used for updates and will be visible within the Langfuse App.
+        I.e. if you want to update a trace, you'd use the same body id, but separate event IDs.
 
         Notes:
+        - Introduction to data model: https://langfuse.com/docs/tracing-data-model
         - Batch sizes are limited to 3.5 MB in total. You need to adjust the number of events per batch accordingly.
