+## Repository Structure
+
+We built a monorepo using [pnpm](https://pnpm.io/motivation) and [turbo](https://turbo.build/repo/docs) to manage the dependencies and build process. The monorepo contains the following packages:
+
+- `web`: is the main application package providing Frontend and Backend APIs for Langfuse.
+- `worker` (no production yet): contains an application for asynchronous processing of tasks. This package is not yet used in production.
+- `shared`: contains shared code between the above packages.
+- `config-eslint`: contains eslint configurations which are shared between the above packages.
+- `config-typescript`: contains typescript configurations which are shared between the above packages.

 6. Start the development server
 
    ```bash
-    npm run dev
+    pnpm run dev
    ```
 
+## Monorepo quickstart
+
+- Available packages and their dependencies
+
+  Packages are included in the monorepo according to the `pnpm-workspace.yaml` file. Each package maintains its own dependencies defined in the `package.json`. Internal dependencies can be added as well by adding them to the package dependencies: `"@langfuse/shared": "workspace:*"`.
+
+- Executing commands
+
+  You can run commands in all packages at once. For example, to install all dependencies in all packages, you can execute:
+
+  ```bash
+  pnpm install
+  pnpm run dev
+  pnpm --filter=web run dev # execute command only in one package
+  ```
+
+  In the root `package.json`, you can find scripts which are executed with turbo e.g. `turbo run dev`. These scripts are executed with the help of Turbo. Turbo executes the commands in all packages taking care of the correct order of execution. Task definitions can be found in the `turbo.config.js` file.
+
+- Run migrations
+
+  To run migrations, you can execute the following command.
+
+  ```bash
+  pnpm --filter=shared run db:migrate
+  ```
+
 > [!NOTE]
-> If you frequently switch branches, use `npm run dx` instead of `npm run dev`. This command will install dependencies, reset the database (wipe and apply all migrations), and run the database seeder with example data before starting the development server.

+## System behavior
+
+### Ingestion API `(/public/api/ingestion)`
+
+- the ingestion API takes different event types (creation and updates of traces, generations, spans, events)
+- The API loops through each event and:
+  - validates the event
+  - stores the event raw in the events table
+  - calculates tokens for `generations`
+  - matches models from the `models` table to model for `generations` events
+  - upserts the event in the `traces` or `observations` table
+- returns a `207` HTTP status code with a list of errors if any event failed to be ingested

-## 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 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))

+### 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.

-#### 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>
-    );
-  }
-  ```

 ### Telemetry
 
-By default, Langfuse automatically reports basic usage statistics to a centralized server (PostHog).
+By default, Langfuse automatically reports basic usage statistics of self-hosted instances to a centralized server (PostHog).

 1. Understand how Langfuse is used and improve the most relevant features.
 2. Track overall usage for internal and external (e.g. fundraising) reporting.
