Description
Current State
The current docs does not have a lot of documentation of APISIX's gRPC support leading to users having to ask questions. @kingluo has documented some notes in a gist: https://gist.github.com/kingluo/65a247c302dd2e518fd3408c70241a77
Desired State
The notes in this gist should be added to the APISIX documentation. It needs to be decided where and how these should be added.
