Everything in 2sxc is multi-language right from the start. It's important to understand that every field in 2sxc can be translated or not - and the lookup happens automatically. So the following examples will automatically show the correct value based on the language you're on.

There are two important types of multi-language:

1. Multi-Language Resources - like messages / button labels etc.
2. Multi-Language Content - things the content editor will work with

The editor can edit anything and choose which field to translate. In the following example, only one book is translated - and even the cover-image is translated.
