-## Replit
-
-Replit may [not support](https://github.com/PrismarineJS/bedrock-protocol/issues/363) the necessary outbound UDP connections required to connect to a Minecraft server. For further assistance using Replit, please contact Replit support or consider using an alternative hosting service if hosting locally is not possible.
-
-Some alternatives:
-* [Gitpod](https://www.gitpod.io/)
-  * Gitpod is a cloud development environment for teams to efficiently and securely develop software, right from your browser.
-* [Github Codespaces](https://github.com/features/codespaces)
-  * A Codespace is a developer environment like Gitpod that's hosted in the cloud, accessed in your browser.
-* [Google Colab](https://colab.research.google.com/)
-  * Google Colab is a Jupyter notebook environment. Jupyter notebook offer a Python environment where you can write, explain, visualize and execute code straight from a web-based developer environment. For more information on using Colab for JavaScript projects, see [Mineflayer on Google Colab](https://colab.research.google.com/github/PrismarineJS/mineflayer/blob/master/docs/mineflayer.ipynb).

 ## Kicked during login
-NOTE: If you not receiving any errors, the error probably logged in debug mode which is not enabled. To enable it, set `process.env.DEBUG = 'minecraft-protocol'` to the top of the file
 
 Some servers can kick you if you don't set `authTitle` as explained in the README.
