Cannot open the link to new rule documentation

It might be the connection problem that people from China cannot open the setup documentation, let alone start to add new rules by their own. Please help to add a new link to the new rule setup documentation, so that people from mainland China can start adding their own rules. I mean if only we can edit all by our own. There is way more potence we can dig.

The issue does not name a documentation file or provide the replacement link. First identify the new-rule setup documentation and confirm an accessible mainland-China link; done means users can open the linked guide and follow it to start adding their own rules.
