-Hello world
+The following low-level docs are aimed at core contributors and cover how to contribute to the Core SDK.
+
+:::tip
+If you are interested to **build on top of the SDK**, like creating assistants or adding app level extensions, please refer to [developer docs](/developer) instead.
+:::
+
+## Core SDK
+
+At its Core, Jan is a cross-platform, local-first and AI native framework that can be used to build anything. In fact, current features are all implemented as 3rd party extensions on top of this Core SDK.
+
+Ultimately, we aim for a VSCode or Obsidian like framework that allows devs to build and customize complex AI applications for their specific needs, in less than 15 minutes.
+
+### Cross Platform
+
+Jan follows [Clean Architecture](https://blog.cleancoder.com/uncle-bob/2012/08/13/the-clean-architecture.html) to the best of our ability. Though leaky abstractions remain (we're a fast moving, open source codebase), we do our best to build an SDK that allows devs to **build once, deploy everywhere.**
+
+Currently, Jan supports:
+
+- `Node Native Runtime`, good for server side apps
+- `Electron Chromium`, good for Desktop Native apps
+- `Capacitor`, good for Mobile apps (planned, not built yet)
+- `Python Runtime`, good for MLOps workflows (planned, not built yet)
+
+Currently, Jan works across:
+
+- Mac Intel & Silicon
+- Windows
+- Ubuntu
+- Nvidia GPUs

+- [Dependency Inversion](https://en.wikipedia.org/wiki/Dependency_inversion_principle)
+
+### Local First
+
+Jan's data persistence happens on the user's local filesystem.
+
+We implemented abstractions on top of `fs` and other core modules in an opinionated way, s.t. user data is saved in a folder-based framework that lets users easily package, export, and manage their data.

+- [Piping Node modules across infrastructures](https://github.com/janhq/jan/tree/main/core/src/node)
+
+### AI Native
+
+All software applications can be natively supercharged with an embedded AI server and AI abstractions.
+
+Including:
+
+- OpenAI Compatible AI [types](https://github.com/janhq/jan/tree/main/core/src/types) and [core extensions](https://github.com/janhq/jan/tree/main/core/src/extensions) to support common functionality like making an inference call.
+- A lightweight, embedded C++ [inference engine](https://github.com/janhq/jan/tree/main/extensions/inference-nitro-extension) that's immediately callable from code.
+
+- [Code Entrypoint](https://github.com/janhq/jan/tree/main/core/src/api)
+
+## Fun Project Ideas
+
+Beyond the current Jan client and UX, the Core SDK can be used to build many other AI-powered and privacy preserving applications.
+
+- `Game engine`: For AI enabled character games, procedural generation games
+- `Health app`: For a personal healthcare app that improves habits
