Shop with different domains by language

[cikcak]

Hello, I have a prestashop with 2 languages. For example: en , fr.

 

Now I can reach it by this: www.mydomain.en/en/ and www.mydomain.en/fr/

 

But I have both domains: mydomain.en and mydomain.fr

 

I would like to reach it by this: mydomain.en/en/ or better - mydomain.en and mydomain.fr or .fr/fr/

 

Is it hard to do this? If languga /en/ use domain.en , if language /fr/ use domain.fr.

 

Or should I do it why multishop? But I really dont need 2 different shops, I just need to use correct domain by language.
