# Migration Guide

This guide covers upgrading to **qb Runtime v1.0.0**, where the names of SDK qb components were unified. Because packages, headers, and module names changed, legacy packages are no longer maintained.

## Installation

### I. Update the APT Package Index

Before installing any packages, update the APT package index:

``` bash
sudo apt update
```

### II. Install the Runtime Library

The runtime library package name changed from `mobilint-npu-runtime` to `mobilint-qb-runtime`.

``` bash
# C++ library
sudo apt install mobilint-qb-runtime

# Python package
pip install mobilint-qb-runtime
```

### III. Install the Driver

Driver package names also changed under the new naming policy, from `aries-driver` to `mobilint-aries-driver`.

``` bash
sudo apt install mobilint-aries-driver
```

## C++ Library Changes

- Compilation / linking flags updated

    ```bash
    # Previous build
    g++ -o example example.cpp -lmaccel

    # Updated build
    g++ -o example example.cpp -lqbruntime
    ```

- Header path updated

    ```cpp
    // Previous header
    # include "maccel/maccel.h"

    // Updated header
    # include "qbruntime/qbruntime.h"
    ```

## Python Package Changes

- Module name updated

    ```python
    # Previous module
    import maccel

    # Updated module
    import qbruntime
    ```
