Engineers coming from traditional RTOS or bare metal backgrounds may initially see Zephyr's meta-tool, West, as an unfamiliar hurdle. While it might seem a bit complex at first, West is actually a simple and effective way to handle multiple repositories, as well as to build, debug, analyze, and more.

In this talk, we’ll break down what West does and how it fits into the Zephyr ecosystem. We'll use plain language and practical examples, showing that West isn’t a barrier at all. Instead, it’s a powerful tool that makes managing your projects easier and more organized.

We'll also explore why West exists and dive into its range of commands. Plus, we'll highlight the opportunities it offers, including enabling capabilities that were not possible without it.

Finally, we’ll demonstrate how to create custom commands with West and provide examples of how you might tailor these commands to meet the specific needs of your applications.
