I want to add Japanese and Chinese page to my English silverstripe site.

I simply tried creating Chinese page few month ago then I forgot how to do it...

I probably looked at some page to set up multi-language page but now I can't find any page to help me.

Any page that show how to create another language page?
I remember it was pretty simple to create new language page and I was so impressed by it.

Thanks

Thanks swaiba
