## Introduction<a name="section11660541593"></a>

The bundle management framework is provided by OpenHarmony for you to manage application bundles \(installation packages\). The following figure shows the architecture of the bundle management framework.

-   **BundleKit**  includes external APIs provided by the Bundle Manager Service, including the APIs for application installation and uninstallation, bundle information query, and bundle state change listeners.
-   The  **bundle scanning sub-module**  parses pre-installed or installed bundles on the local device and extracts information from them for the bundle management sub-module to manage and make the information persistent for storage.

-   The  **bundle installation sub-module**  installs, uninstalls, and updates a bundle.
-   The  **bundle installation service**  is an independent process used to create or delete installation directories and has high permissions.

-   The  **bundle management sub-module**  manages information related to application bundles and stores persistent bundle information.

-   The  **bundle security management sub-module**  verifies signatures, and grants and manages permissions.

```

-   The Bundle Manager Service is running in the foundation process.
-   The Bundle Manager Service is registered with  **sa\_manager**.  **sa\_manager**  runs in the foundation process and sets up a thread runtime environment for the service. For details about how to create and use the Bundle Manager Service, see  [SA Framework](en-us_topic_0000001051589563.md).
-   The Bundle Manager Service starts upon OS startup.
-   You can use the bm tool to install the specified HAP. \(Taking  **hispark\_taurus**  as an example, you can obtain the bm tool from the  **out/hispark\_taurus/ipcamera\_hispark\_taurus/dev\_tools/bin directory**  after the version building.\)

```
./bin/bm install -p /nfs/xxxx.hap
```
