ProtoJSON Format doc page does not describe how to generate JSON #289

The documentation page: https://protobuf.dev/programming-guides/json/

The page sub-heading states that the page "Covers how to use the Protobuf to JSON conversion utilities." However, there is no information on how to generate a JSON file. The page only discusses caveats and edge cases regarding the JSON conversion.

I would like to see a section or link to a section that gives instructions on how use protoc or any other tool to actually create the JSON.
