+The next page just ask for basic configuration options like your
+location, the time zone and keyboard layout. The location is used to
+select a download server near you to speedup updates. The installer is
+usually able to auto detect those setting, so you only need to change

+use some special keyboard layout not commonly used in your country.

+You then need to specify an email address and the superuser (root)
+password. The password must have at least 5 characters, but we highly
+recommend to use stronger passwords - here are some guidelines:
+
+- Use a minimum password length of 12 to 14 characters.
+
+- Include lowercase and uppercase alphabetic characters, numbers and symbols.
+
+- Avoid character repetition, keyboard patterns, dictionary words,
+  letter or number sequences, usernames, relative or pet names,
+  romantic links (current or past) and biographical information (e.g.,
+  ID numbers, ancestors' names or dates).
+
+It is sometimes necessary to send notification to the system
+administrator, for example:
+
+- Information about available package updates.
+
+- Error messages from periodic CRON jobs.
+
+All those notification mails will be sent to the specified email
+address.

 The last step is the network configuration. Please note that you can
 use either IPv4 or IPv6 here, but not both. If you want to configure a
 dual stack node, you can easily do that after installation.

 If you press `Next` now, installation starts to format disks, and
 copies packages to the target. Please wait until that is finished,
 then reboot the server.
