## Troubleshooting

As Jan is in development mode, you might get stuck on a broken build.

To reset your installation:

1. Use the following commands to remove any dangling backend processes:

   ```sh
   ps aux | grep nitro
   ```

   Look for processes like "nitro" and "nitro_arm_64," and kill them one by one with:

   ```sh
   kill -9 <PID>
   ```

2. **Remove Jan from your Applications folder and Cache folder**

   ```bash
   make clean
   ```

   This will remove all build artifacts and cached files:

   - Delete Jan extension from your `~/jan/extensions` folder
   - Delete all `node_modules` in current folder
   - Clear Application cache in `~/Library/Caches/jan`

## Requirements for running Jan

- MacOS: 13 or higher
- Windows:
  - Windows 10 or higher
  - To enable GPU support:
    - Nvidia GPU with CUDA Toolkit 11.7 or higher
    - Nvidia driver 470.63.01 or higher
- Linux:
  - glibc 2.27 or higher (check with `ldd --version`)
  - gcc 11, g++ 11, cpp 11 or higher, refer to this [link](https://jan.ai/guides/troubleshooting/gpu-not-used/#specific-requirements-for-linux) for more information
  - To enable GPU support:
    - Nvidia GPU with CUDA Toolkit 11.7 or higher
    - Nvidia driver 470.63.01 or higher

## Contributing

Contributions are welcome! Please read the [CONTRIBUTING.md](CONTRIBUTING.md) file

### Pre-requisites

- node >= 20.0.0
- yarn >= 1.22.0
- make >= 3.81

### Instructions

1. **Clone the repository and prepare:**

   ```bash
   git clone https://github.com/janhq/jan
   cd jan
   git checkout -b DESIRED_BRANCH
   ```

2. **Run development and use Jan Desktop**

   ```bash
   make dev
   ```

This will start the development server and open the desktop app.

3. (Optional) **Run the API server without frontend**

   ```bash
   yarn dev:server
   ```

### For production build

```bash
# Do steps 1 and 2 in the previous section
# Build the app
make build
```

This will build the app MacOS m1/m2 for production (with code signing already done) and put the result in `dist` folder.

### Docker mode

- Supported OS: Linux, WSL2 Docker
- Pre-requisites:

  - Docker Engine and Docker Compose are required to run Jan in Docker mode. Follow the [instructions](https://docs.docker.com/engine/install/ubuntu/) below to get started with Docker Engine on Ubuntu.

    ```bash
    curl -fsSL https://get.docker.com -o get-docker.sh
    sudo sh ./get-docker.sh --dry-run
    ```

  - If you intend to run Jan in GPU mode, you need to install `nvidia-driver` and `nvidia-docker2`. Follow the instruction [here](https://docs.nvidia.com/datacenter/cloud-native/container-toolkit/latest/install-guide.html) for installation.

    ```

  - **Step 2**: Visit [NVIDIA NGC Catalog ](https://catalog.ngc.nvidia.com/orgs/nvidia/containers/cuda/tags) and find the smallest minor version of image tag that matches your CUDA version (e.g., 12.1 -> 12.1.0)

  - **Step 3**: Update the `Dockerfile.gpu` line number 5 with the latest minor version of the image tag from step 2 (e.g. change `FROM nvidia/cuda:12.2.0-runtime-ubuntu22.04 AS base` to `FROM nvidia/cuda:12.1.0-runtime-ubuntu22.04 AS base`)

  - **Step 4**: Run command to start Jan in GPU mode

    ```bash
    # GPU mode with default file system
    docker compose --profile gpu-fs up -d

    # GPU mode with S3 file system
    docker compose --profile gpu-s3fs up -d
    ```

This will start the web server and you can access Jan at `http://localhost:3000`.

> Note: RAG feature is not supported in Docker mode with s3fs yet.
