After learning how to get started through the guides on the official website of spring, how to view the more detailed documentation of the project?

for example, I learned about the introduction to spring websocket through the following URL
ides/gs/messaging-stomp-websocket/" rel=" nofollow noreferrer "> https://spring.io/guides/gs/m.

but guides only talks about broadcast websocket, but I want to know how to implement the peer-to-peer websocket function. Is there any in-depth guides that you can check?

or how to find a matching documention

below is the document I found, but I find that the content of the document is not easy to understand

https://docs.spring.io/spring.

is there any more matching document content? What is the correct way to find it?
