513You will probably only use one or maybe two locales on your system. You have to
514specify locales you will need in <path>/etc/locale.gen</path>.

517<pre caption="Opening /etc/locale.gen">

522The following locales are an example to get both English (United States) and
523German (Germany) with the accompanying character formats (like UTF-8).

525
526<pre caption="Specify your locales">

528en_US.UTF-8 UTF-8

530de_DE@euro ISO-8859-15
531</pre>
532
533<note>
534You can select your desired locales in the list given by running <c>locale -a</c>.
535</note>
536
537<p>
538The next step is to run <c>locale-gen</c>. It will generates all the locales you
539have specified in the <path>/etc/locale.gen</path> file.

541
542<pre caption="Running locale-gen">
543# <i>locale-gen</i>

547Once done, you now have the possibility to set the system-wide locale settings
548in the <path>/etc/env.d/02locale</path> file:
