Disclaimers:

• Due to BetaEvolutions editing a lot of stuff, it is highly recommended that you do not use other mods whilst using it.
  

(Language file edits, terrain edits and so on, are compatible, so long as BetaEvo doesn't conflict with it.)

• This guide is written with MultiMC & its forks in mind; while you can install BetaEvolutions on other launcher other than the official one, support may not be provided.
• Make a ticket on the Discord guild if you're encountering issues.
• In the event you encounter an error related to Discord RPC & if the game shows up with broken colors, please reference the BetaEvolutions/Apple Silicon Mac install guide.
