Does Alizee theme support two languages for readers to switch according to their own wish? how?
Hi, an easy way is to use plugin that direct you to external translation services.
Here is all about it.
More proper way is to use POEdit and create translations in desired languages. In this way you must have all your WP content translated manually in number of languages that you are using.
And of course you should use for ex. Polylang plugin to add language switcher to your page.
