Making single domain multi site

I have a multi language site of English and Japanese, I originally just wanted to make an English site but I reside in Japan and many of my friends are Japanese and they recommended to make it to bilingual……so I tried qtanslate-x first with Fashonista. Once it was working but when I switch to Auberge, it failed. I research for an alternative and found xili language plugin. I feel having different language posts separately is better way than having them as one post. I still have few problems to fix but thanks to xili language, my site is up and running ?? They are also nice with mail support too!
