# Overview<a name="EN-US_TOPIC_0000001051452100"></a>

This document describes how to develop OpenHarmony bundles and distributions, and how to create, develop, and build code, as well as burn and debug devices by using a command line tool.

-   A bundle usually maps onto a code repository, which is a code archive with the  **bundle.json**,  **README**, and  **LICENSE**  files.
-   A distribution consists of multiple bundles. Each distribution integrates various bundles of a comprehensive system, such as the driver, kernel, framework, and applications. These bundles can be used for device burning.
