+## Overview
+
+[Nitro](https://github.com/janhq/nitro) is an inference server on top of [llama.cpp](https://github.com/ggerganov/llama.cpp). It provides an OpenAI-compatible API, queue, & scaling.
+
+Nitro is the default AI engine downloaded with Jan. There is no additional setup needed.

+
+Users with Nvidia GPUs can get **20-40% faster\* token speeds** on their laptop or desktops by using [TensorRT-LLM](https://github.com/NVIDIA/TensorRT-LLM). The greater implication is that you are running FP16, which is also more accurate than quantized models.
+
+This guide walks you through how to install Jan's official [TensorRT-LLM Extension](https://github.com/janhq/nitro-tensorrt-llm). This extension uses [Nitro-TensorRT-LLM](https://github.com/janhq/nitro-tensorrt-llm) as the AI engine, instead of the default [Nitro-Llama-CPP](https://github.com/janhq/nitro). It includes an efficient C++ server to natively execute the [TRT-LLM C++ runtime](https://nvidia.github.io/TensorRT-LLM/gpt_runtime.html). It also comes with additional feature and performance improvements like OpenAI compatibility, tokenizer improvements, and queues.
+
+*Compared to using LlamaCPP engine.
+
+:::warning
+This feature is only available for Windows users. Linux is coming soon.
+
+Additionally, we only prebuilt a few demo models. You can always build your desired models directly on your machine. [Read here](#build-your-own-tensorrt-models).
+
+:::
+
+## Requirements
+
+- A Windows PC
+- Nvidia GPU(s): Ada or Ampere series (i.e. RTX 4000s & 3000s). More will be supported soon.
+- 3GB+ of disk space to download TRT-LLM artifacts and a Nitro binary
+- Jan v0.4.9+ or Jan v0.4.8-321+ (nightly)
+- Nvidia Driver v535+ ([installation guide](https://jan.ai/guides/common-error/not-using-gpu/#1-ensure-gpu-mode-requirements))
+- CUDA Toolkit v12.2+ ([installation guide](https://jan.ai/guides/common-error/not-using-gpu/#1-ensure-gpu-mode-requirements))
+
+## Install TensorRT-Extension
+
+1. Go to Settings > Extensions
+2. Click install next to the TensorRT-LLM Extension
+3. Check that files are correctly downloaded
+
+```sh
+ls ~\jan\extensions\@janhq\tensorrt-llm-extension\dist\bin
+# Your Extension Folder should now include `nitro.exe`, among other artifacts needed to run TRT-LLM
+```
+
+## Download a Compatible Model
+TensorRT-LLM can only run models in `TensorRT` format. These models, aka "TensorRT Engines", are prebuilt specifically for each target OS+GPU architecture.
+
+We offer a handful of precompiled models for Ampere and Ada cards that you can immediately download and play with:
+
+1. Restart the application and go to the Hub
+2. Look for models with the `TensorRT-LLM` label in the recommended models list. Click download. This step might take some time. 🙏
+
+![image](https://hackmd.io/_uploads/rJewrEgRp.png)
+
+3. Click use and start chatting!
+4. You may need to allow Nitro in your network 
+
+![alt text](image.png)
+
+:::warning
+If you are our nightly builds, you may have to reinstall the TensorRT-LLM extension each time you update the app. We're working on better extension lifecyles - stay tuned.
+:::
+
+## Configure Settings
+
+You can customize the default parameters for how Jan runs TensorRT-LLM. 
+
+:::info
+coming soon
+:::
+
+## Troubleshooting
+
+### Incompatible Extension vs Engine versions
+
+For now, the model versions are pinned to the extension versions.
+
+### Uninstall Extension
+
+1. Quit the app
+2. Go to Settings > Extensions
+3. Delete the entire Extensions folder.
+4. Reopen the app, only the default extensions should be restored.
+
+### Install Nitro-TensorRT-LLM manually
+
+To manually build the artifacts needed to run the server and TensorRT-LLM, you can reference the source code. [Read here](https://github.com/janhq/nitro-tensorrt-llm?tab=readme-ov-file#quickstart).
+
+### Build your own TensorRT models

+# Tensorrt-LLM Extension
+
+Created using Jan extension example
+
+# Create a Jan Extension using Typescript
+
+Use this template to bootstrap the creation of a TypeScript Jan extension. 🚀
+
+## Create Your Own Extension
+
+To create your own extension, you can use this repository as a template! Just follow the below instructions:
+
+1. Click the Use this template button at the top of the repository
+2. Select Create a new repository
+3. Select an owner and name for your new repository
+4. Click Create repository
+5. Clone your new repository
+
+## Initial Setup
+
+After you've cloned the repository to your local machine or codespace, you'll need to perform some initial setup steps before you can develop your extension.
+
+> [!NOTE]
+>
+> You'll need to have a reasonably modern version of
+> [Node.js](https://nodejs.org) handy. If you are using a version manager like
+> [`nodenv`](https://github.com/nodenv/nodenv) or
+> [`nvm`](https://github.com/nvm-sh/nvm), you can run `nodenv install` in the
+> root of your repository to install the version specified in
+> [`package.json`](./package.json). Otherwise, 20.x or later should work!
+
+1. :hammer_and_wrench: Install the dependencies
+
+   ```bash
+   npm install
+   ```
+
+1. :building_construction: Package the TypeScript for distribution
+
+   ```bash
+   npm run bundle
+   ```
+
+1. :white_check_mark: Check your artifact
+
+   There will be a tgz file in your extension directory now
+
+## Update the Extension Metadata
+
+The [`package.json`](package.json) file defines metadata about your extension, such as
+extension name, main entry, description and version.
+
+When you copy this repository, update `package.json` with the name, description for your extension.
+
+## Update the Extension Code
+
+The [`src/`](./src/) directory is the heart of your extension! This contains the
+source code that will be run when your extension functions are invoked. You can replace the
+contents of this directory with your own code.
+
+There are a few things to keep in mind when writing your extension code:
+
+- Most Jan Extension functions are processed asynchronously.
+  In `index.ts`, you will see that the extension function will return a `Promise<any>`.
+
+  ```typescript
+  import { events, MessageEvent, MessageRequest } from '@janhq/core'
+
+  function onStart(): Promise<any> {
+    return events.on(MessageEvent.OnMessageSent, (data: MessageRequest) =>
+      this.inference(data)
+    )
+  }
+  ```
+
+  For more information about the Jan Extension Core module, see the
+  [documentation](https://github.com/janhq/jan/blob/main/core/README.md).
+
+So, what are you waiting for? Go ahead and start customizing your extension!
