-### Database Overview
+**Langfuse v3 (work in progress, not released yet)**
 
-The diagram below may not show all relationships if the foreign key is not defined in the database schema. For instance, `trace_id` in the `observation` table is not defined as a foreign key to the `trace` table to allow unordered ingestion of these objects, but it is still a foreign key in the application code.
+> [!NOTE]
+> Infrastructure will change in Langfuse version 3.0. More in the [GitHub Discussions](https://github.com/orgs/langfuse/discussions/1902).
+> `langfuse/langfuse/worker` is under active development and not recommended for production use in Langfuse 2.x.

+## 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.
+- `packages`:
+  - `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.
+- `ee`: contains all enterprise features. See [EE README](ee/README.md) for more details.
+
 ## Development Setup
 
 Requirements
 
 - Node.js 20 as specified in the [.nvmrc](.nvmrc)
+- Pnpm v.9.5.0
 - Docker to run the database locally
 
+**Note:** You can also simply run Langfuse in a **GitHub Codespace** via the provided devcontainer. To do this, click on the green "Code" button in the top right corner of the repository and select "Open with Codespaces".
+
 **Steps**

-5. Install dependencies
+5. Run the migrations
+
+   All database migrations and configs are in the `shared` package.

+
+   Password: password
+
+## 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 run db:migrate -- --name <name of the migration>
+  ```
+
 > [!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

 1. The Docker image is published to GitHub Packages with the version number and `latest` tag.
 2. The deployment is carried out on Langfuse Cloud. This is done by force pushing the `main` branch to the `production` branch during every release, using the [`release.yml`](.github/workflows/release.yml) GitHub Action.
 
+## Theming
+
+At Langfuse, we utilize CSS variables to manage our theme settings across the platform.
+
+Our approach leverages separate CSS variables for backgrounds (--background) and foregrounds (--foreground), fully adhering to the [shadcn/ui](https://ui.shadcn.com/docs/theming) color conventions. The background suffix can be omitted if the variable is used for the background color of the component. We recommend using HSL values for these colors to enhance consistency and customization. There is no need to manually handle dark mode styling with "dark:" prefixes, as next-themes automatically manages the theme switching.
+
+Given the following CSS variables:
+
+```
+--primary: 222.2 47.4% 11.2%; // e.g. background-color
+--primary-foreground: 210 40% 98%; // e.g. text-color
+```
+
+The background color of the following component will be `hsl(var(--primary))` and the foreground color will be `hsl(var(--primary-foreground))`.
+
+```
+<div class="bg-primary text-primary-foreground">Hello</div>
+```
+

+### Adding New Colors
+
+1. Global Definitions: Add new CSS variable definitions in the global.css file.
+2. Tailwind Configuration: Reflect these new colors in the tailwind.config.js to maintain alignment with Tailwind's utility classes.
+
+By following these guidelines, you can ensure that any contributions to our theme are consistent, maintainable, and aligned with our design system.
+
+## Maintainers
+
+### Using secrets stored in 1Password
+
+When applying changes to non-local environments, you may need to use secrets stored in 1Password. We use the 1Password CLI for this purpose.
+
+Example:
+
+```bash
+op run --env-file="./.env" -- pnpm --filter=shared run db:deploy
+```

-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.

 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.
