About this Modpack

A modpack to help optimise servers.

What does this modpack contain?

Exact same gameplay to vanilla minecraft
Heavily optimises the server.
Has simple voicechat (the mod is also needed client-side).
Any game version from at least 1.8.x can join to most recent

No Bedrock cross play as I am pretty sure that the player will need to edit the mod's jar itself to do so.

How will you copy this into the server?

Download the mrpack.
Open it in modrinthapp.
Go to the more button next to settings on the modpack and press open file location.
Lastly, copy all the mods to a FABRIC server, this I cannot help you with as everyone would definitely be using different types of servers.
