# Cross-Platform and Platform-Specific Development

Qt allows you to write advanced applications and UIs once, and deploy them across desktop and embedded operating systems without rewriting the source code. The top section of this page provides an overview of the tools and techniques used in Qt application development. Still, you might want to add platform-specific features to your code. The bottom section of the page links to documents that describe platform-specific features provided by Qt, and discuss issues related to particular platforms and environments.

## Cross-Platform Development with Qt

Qt is provided with a set of build tools to help developers automate the process of building and installing Qt applications.
