Synchronizing and Sharing Settings in 2017

I've found this topic for idea 2016, but I can' follow the instruction on my 2017 app https://www.jetbrains.com/help/idea/2016.2/synchronizing-and-sharing-settings.html

There's a link that's supposed to point to similar instructions for current ver but it's a 404 https://www.jetbrains.com/help/idea?topic=topicId305513

When browsing the 2017 docs I still can't find what I'm looking for https://www.jetbrains.com/help/idea/tuning-intellij-idea.html

Anyone can help?
