-## What is Langfuse?
+## Overview
 
-Langfuse is an open source observability & analytics solution for LLM-based applications. It is mostly geared towards production usage but some users also use it for local development of their LLM applications.
+### Develop
 
-Langfuse is focused on applications built on top of LLMs. Many new abstractions and common best practices evolved recently, e.g. agents, chained prompts, embedding-based retrieval, LLM access to REPLs & APIs. These make applications more powerful but also unpredictable for developers as they cannot fully anticipate how changes impact the quality, cost and overall latency of their application. Thus Langfuse helps to monitor and debug these applications.
+- **Observability:** Instrument your app and start ingesting traces to Langfuse ([Quickstart](https://langfuse.com/docs/get-started), [Integrations](https://langfuse.com/docs/integrations) [Tracing](https://langfuse.com/docs/tracing))
+- **Langfuse UI:** Inspect and debug complex logs ([Demo](https://langfuse.com/docs/demo), [Tracing](https://langfuse.com/docs/tracing))
+- **Prompts:** Manage, version and deploy prompts from within Langfuse ([Prompt Management](https://langfuse.com/docs/prompts))
 
-**Demo (2 min)**
+### Monitor
+
+- **Analytics:** Track metrics (cost, latency, quality) and gain insights from dashboards & data exports ([Analytics](https://langfuse.com/docs/analytics))
+- **Evals:** Collect and calculate scores for your LLM completions ([Scores & Evaluations](https://langfuse.com/docs/scores))
+  - Run model-based evaluations ([Model-based evaluations](https://langfuse.com/docs/scores/model-based-evals))
+  - Collect user feedback ([User Feedback](https://langfuse.com/docs/scores/user-feedback))
+  - Manually score observations in Langfuse ([Manual Scores](https://langfuse.com/docs/scores/manually))
+
+### Test
+
+- **Experiments:** Track and test app behaviour before deploying a new version
+  - Datasets let you test expected in and output pairs and benchmark performance before deployiong ([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))

-Langfuse offers an admin UI to explore the ingested data.
-
-- Nested view of LLM app executions; detailed information along the traces on: latency, cost, scores
-- Segment execution traces by user feedback, to e.g. identify production issues

+### Ingesting Data · Instrumenting Your Application
 
-#### Langchain applications
+Note: We recommend using our fully async, typed [SDKs](https://langfuse.com/docs/sdk) that allow you to instrument any LLM application with any underlying model. They are available in [Python](https://langfuse.com/docs/sdk/python) & [JS/TS](https://langfuse.com/docs/sdk/typescript). The SDKs will always be the most fully featured and stable way to ingest data into Langfuse.
 
-The Langfuse callback handler automatically instruments Langchain applications. Currently available for Python and JS/TS.
+You may want to use another integration to get started quickly or implement a use case that we do not yet support. However, we recommend to migrate to the Langfuse SDKs over time to ensure performance and stability.
 
-**Python**
+See our the [→ Quickstart](https://langfuse.com/docs/get-started) to get started in integrating Langfuse.
 
-```shell
-pip install langfuse

-#### Add scores/evaluations to traces (optional)
+### Support and feedback
 
-Quality/evaluation of traces is tracked via scores ([docs](https://langfuse.com/docs/scores)). Scores are related to traces and optionally to observations. Scores can be added via:
+In order of preference the best way to communicate with us:
 
-- **Backend SDKs** (see docs above): `{trace, event, span, generation}.score()`
-- **API** (see docs below): `POST /api/public/scores`
-- **Client-side using Web SDK**, e.g. to capture user feedback or other user-based quality metrics:
-
-  ```sh
-  npm install langfuse
-  ```
-
-  ```ts
-  // Client-side (browser)
-
-  import { LangfuseWeb } from "langfuse";
-
-  const langfuseWeb = new LangfuseWeb({
-    publicKey: process.env.LANGFUSE_PUBLIC_KEY,
-  });
-
-  // frontend handler (example: React)
-  export function UserFeedbackComponent(props: { traceId: string }) {
-    const handleUserFeedback = async (value: number) => {
-      await langfuseWeb.score({
-        traceId: props.traceId,
-        name: "user_feedback",
-        value,
-      });
-    };
-    return (
-      <div>
-        <button onClick={() => handleUserFeedback(1)}>👍</button>
-        <button onClick={() => handleUserFeedback(-1)}>👎</button>
-      </div>
-    );
-  }
-  ```

-
-              1.  **Functional Component**:
-              
-              A functional component is just a plain JavaScript function that accepts props as an argument, and returns a React element. Here's how you can create one:
-              
-              
-              'import React from 'react';  function Greeting(props) {   return <h1>Hello, {props.name}</h1>; }  export default Greeting;'
-              
-              To use this component in another file, you can do:
-              
-              
-              'import Greeting from './Greeting';  function App() {   return (     <div>       <Greeting name="John" />     </div>   ); }  export default App;'
-              
-              2.  **Class Component**:
-              
-              You can also define components as classes in React. These have some additional features compared to functional components:
-              
-              
-              'import React, { Component } from 'react';  class Greeting extends Component {   render() {     return <h1>Hello, {this.props.name}</h1>;   } }  export default Greeting;'
-              
-              And here's how to use this component:
-              
-              
-              'import Greeting from './Greeting';  class App extends Component {   render() {     return (       <div>         <Greeting name="John" />       </div>     );   } }  export default App;'
-              
-              With the advent of hooks in React, functional components can do everything that class components can do and hence, the community has been favoring functional components over class components.
-              
-              Remember to import React at the top of your file whenever you're creating a component, because JSX transpiles to 'React.createElement' calls under the hood.`,
