 After following the above steps the Raspberry Pi will provide a wifi network named under the essid `kolibri` without any password.

+After connecting a device to this wifi network provided by the Raspberry, you can open the url http://10.10.10.10 in a browser will allow you enjoy all the features of a working Kolibri server. 
 
 By default the server does not have Internet access. To add content channels to Kolibri you can either connect an usb disk with content or plug and ethernet cable with Internet access.
 
 In case you want to login into the server, the user is `pi` and the password is `kolibrifly`
 
+VERY IMPORTANT: After installing the image, a ssh server is installed with a known password. CHANGE IT in case you want to connect it to Internet or be used by people who could mess it up.
