From where? Isn’t that coming from whoever provides that protocol service? But i guess you should start here V2Ray - ArchWiki
This section is outdated. GUI does not support this protocol. the xray section to which your section refers is not yet created
Did you notice the date of the last post? 
Replying to old threads is referred to as necrobumping and is generally discouraged, as mentioned in the forum rules.
However, if you have a link that supports the accuracy of your comment, I’m sure that might be beneficial for others finding this thread.
Cheers.
