How can I localize Eruption?
To localize your WordPress installation to allow the translation of your content you must use one of the localization plugins available (eg. WPML, ZdMultiLang, etc.).
To translate the theme’s strings in another language, we suggest that you follow the instructions in this page: http://codex.wordpress.org/Translating_WordPress.
Eruption’s strings are translation-ready as they’re wrapped with the gettext syntax “__(your string)” that allows translation.
