## Introduction
Over the years, the Chromium DevTools have grown to include a large array of specialized tools—about 30 at time of writing—to help web developers troubleshoot web applications. Some, like **Elements** and **Console**, may be used daily, while others, like **Sensors** and **Performance monitor,** may have more specialized but infrequent use.
DevTools users tell us that a side effect of having numerous tools is that the overall experience can be visually and conceptually overwhelming. New web developers may not have a clear idea of where to start and how to explore and use the DevTools. More experienced developers may find themselves in one or two familiar workflows that want to focus in on.
