+To create a new locale:
+- Copy lang/en_US.utf8.php to a new file (e.g. `lang/es_ES.utf8.php`)
+- Edit the new file, change "class DefaultLang" to "class Lang" so it looks like this:
+```
+
+<?php
+class Lang {
+    public function __construct() {
+       ...
+    }
+}
+
+```
+- Translate all array assignments, e.g. `$array["page.permanent.ban"] = 'Baneo Permanente';`
+- Edit settings.php, set `this->lang` to your locale. Example: `$this->lang = 'es_ES.utf8';`
+
+All messages not translated by the main locale will be translated by the fallback locale (en_US.utf8).
+Thus, if your locale is outdated (if new messages are added to en_US), those new messages will be in English.
