-Use the power supply and turn on PiKVM. The Mini comes with USB-C 5V power supply, and Plus with Barrel 12V. Use the appropriate connector on the **front** side. Please note that Plus can also work from 5V, in this case, do not connect a 12V power supply and don't create a significant power load on USB (external flash sticks, cameras, and so on).

+After turning on the power, PiKVM OS generates unique SSH keys and certificates and performs all necessary operations on the memory card. It takes a few minutes. Do **not** turn off the device until it's fully booted for the first time. Once it's done, the PiKVM will show a greeting on the built-in display.

 ## Connect and set up
 
-### Obtain IP address
+By default, PiKVM receives a dynamic IP address via DHCP and shows it on the OLED display. Let's assume that PiKVM has received the address `192.168.0.100` and has also been assigned a hostname `pikvm`.
 
-### Connect via SSH
+Type the URL in the browser's address bar and press Enter: https://192.168.0.100/ or https://pikvm/.
 
-### Change the default passwords

+### Change the default passwords
+
+For security's sake, it's best to change the default passwords immediately after running PiKVM for the first time. To do that:
+
+1. Open the web terminal
+
+![MISSING SCREENSHOT](web-terminal.png)
+
+2. Gain superuser privileges, use `root` for password:
+
+    ```console
+    $ su -
+    ```
+
+3. Run `rw` to change the access to the SD card to the write mode:
+
+    ```console
+    [root@pikvm ~]# rw
+    ```
+
+4. Change the password for the superuser:
+
+    ```console
+    [root@pikvm ~]# passwd root
+    ```
+
+5. Change the password for web access:
+
+    ```console
+    [root@pikvm ~]# kvmd-htpasswd set admin
+    ```
+
+6. Run `ro` to change the access to the SD card to the read-only mode:
