Configure regions, markets, and locales
Markets and languages determine which variants of a document are delivered.
Locales (languages)
Locales are the language versions (e.g. de, en-US). A document can carry several locales; per site you set which languages it supports.
Markets
Markets are a dimension of their own alongside language — for example for different legal jurisdictions. They’re assigned to sites and serve as an axis along which content can vary.
Site profiles
Site profiles describe the context of a delivery (such as B2C, B2B, or checkout). Together with locale and market they form the axes along which overrides apply and variants are delivered.
