 # hanabi-bot
 A deterministic NodeJS bot that plays on the [hanab.live](https://hanab.live/) interface. Basic structure and ideas were taken from [Zamiell's example bot](https://github.com/Zamiell/hanabi-live-bot) (Python).
 
-Currently, it plays around level 4 of [H-Group](https://hanabi.github.io/). The goal of the bot is to play with humans, so it should be able to handle suboptimal play within reason. However, it still expects that the conventions are followed (in terms of focus, chop, etc.) and does not perform any "learning".
