# Get started
This Quick Start Guide helps you to set up the Qualcomm^®^ RB3 Gen 2 Development Kit to explore and try out end-to-end multimedia and AI applications in a Linux-based environment.
Additionally, this guide provides instructions on how to establish essential communication with host computers running Linux, Windows^®^, and macOS^®^.
Note
Qualcomm^®^ Linux^®^ allows you to develop applications for all SoCs listed at [Hardware SoCs](https://docs.qualcomm.com/bundle/publicresource/topics/80-70018-115/soc.html). Different development kits support specific SoCs. This Quick Start Guide applies to QCS6490 and QCS5430.
