| [What is DataDike SONAR](/sonar/get-started/what-is-datadike-sonar.md) | What DataDike SONAR does, who works with it, and where its scope ends.                                                                                    |
| [Architecture and components](/sonar/get-started/architecture.md)      | The parts SONAR is made of, on the server and on each endpoint, how a command travels to a device and back, and what stops working when one part is down. |
| [Core concepts](/sonar/get-started/core-concepts.md)                   | The vocabulary SONAR uses — clients, sites, devices, status, policies, checks, tasks, alerts, employees, roles — and how the objects relate.              |
| [A tour of the console](/sonar/get-started/console-tour.md)            | How the console is laid out: the sidebar groups, the header menus, the Home dashboard, and the path from the clients overview to a device and its tabs.   |
| [Onboard your first device](/sonar/get-started/first-device.md)        | From an empty console to a first device online: create a client and a site, generate the agent installer, run it, and confirm the device reports.         |
