[coderdiaz]

Currently, the CVfolio project supports only content on English. The next approach is to support multiples languages like Spanish.

Today, we only have a page for generate the next pages like homepage, projects and posts.

We need to add a prefix for allow content in different languages like:

/ - default content on English
/es - content on Spanish
