#### Existing language

Let's say you want to translate a page for a language that already has translations for some pages, like Spanish.

In the case of Spanish, the 2-letter code is `es`. So, the directory for Spanish translations is located at `docs/es/`.

/// tip

The main ("official") language is English, located at `docs/en/`.

///

Now run the live server for the docs in Spanish:

	// Verify that certificate provided by user is issued by trusted CA,

Thuật ngữ "cấu trúc" (schema) cũng có thể được coi như là hình dạng của dữ liệu, tương tự như một JSON content.
