Shattered Prism is a custom launcher for Minecraft that allows you to easily manage multiple installations of Minecraft at once.
This is a fork of FjordLauncher and is not endorsed by it or Prism.
## Why does this exist?
This project was originally a direct fork of upstream Prism, but spent most of it's time as a small group-oriented continuation of fn2006's PollyMC, except with continued support for Microsoft authentication and being without branding that would get it confused for a uh... *similarly named project*. Luckily though, [@evan-goode](https://github.com/evan-goode) eventually created Fjord and this project has been based upon it ever since!
## Differences from PrismLauncher
- Fully removed PrismLauncher's DRM.
- Restores the ability to download modpacks from FTB.
- [Support for alternative auth servers](doc/alternative-auth-servers.md).
## Installation

## Building
To build the launcher yourself, follow the instructions on the Prism Launcher website, but clone this repo instead:
- [Windows](https://prismlauncher.org/wiki/development/build-instructions/windows/)
- [Linux](https://prismlauncher.org/wiki/development/build-instructions/linux/)

## Notes
- You can easily use a custom version of authlib-injector on an instance. Select the instance in the main window, click "Edit" (or Ctrl+I/Command+I), go to the Version tab, click "Add Agents", and select your authlib-injector JAR. If your JAR is not correctly identified as authlib-injector, make sure the `Agent-Class` field in the JAR's MANIFEST.MF is `moe.yushi.authlibinjector.Premain`.
