+After entering the Home Assistant device's address in your browser's address bar, the preparation screen is shown. Depending on your hardware, preparation may take a while.

-Next, you can enter a name for your home and set your location and unit system. Select **Detect** to find your location and set your time zone and unit system based on that location. If you'd rather not send your location, you can set these values manually.
+To show the logs, select the blue pulsing circle.
