Add i18n on Adonis Page/Documentation

[lKk2]

Since this project has been growing a lot at least in Brazilian Community i would like to suggest the addition of i18n support since most of them doesnt know English well.

Btw: i'm willing to help you guys on the ptBR translation if needed.

Hey @lKk2!

It's planned to allow the community to translate the website. We will do the same way as React does.

But first of all, we need to finish the english documentation, I'll let you know when you can start working on it!
