my json5 library, Jankson, has a discord now ( https://discord.gg/nAPns7EZ )
Seriously though, you can:
* Ask unreasonable jankson questions
* Send issues too small for an Issue
* Be lazy and send issues big enough for an Issue
* Contribute to [badly needed!] documentation
* Contribute code
* Influence the design of a major rework
With the Document API you'll be able to better inspect and *physically change/reorder* comments and line breaks; detect and preserve "doc" comments; put comments and formatting in some places Jankson did not previously preserve; and deserialize full nested generics and records.
