Building v3 OHIF

I have followed Build for Production | OHIF and was able to deploy OHIF viewer just fine at But it is not v3. How do i build v3 version?
Also i have noticed v3 does not have all translations, is there a way to use translation from previuous version?

please use v3-stable branch as the target branch for OHIF-V3

Thank you, successfuly built v3.
What about russian translation? I have joined Locize and found that translation is 100% complete. How to add it to viewer?
