The README.md needs updating to include the new Chat events relayed to and from Discord/Minecraft - these are found in the config class here:

The following unlisted events are:

• Discord events relayed to Minecraft
  • A user sent a message in reply to another
• Minecraft events relayed to Discord
  • A player sent an in-game message via the /me command
  • An admin broadcast an in-game message via the /say command
  • An admin broadcast an in-game message to all players via the /tellraw @a command

Can I try to work on this?

I think the Minecraft event of 'A player sent an in game message via the /me command' is already added to the README....
