 This is a [Fabric](https://fabricmc.net/) mod that can run on both clients and servers.
 Because the mod is relatively simple, Fabric API is not required and just having Fabric Loader works fine.
 
-On servers it functions as an authentication provider while running on Offline Mode by RPCing with the [Mince](https://git.flash.moe/flashii/mince) project.
+On servers it functions as an authentication provider while running on Offline Mode by RPCing with the [Mince](https://patchii.net/flashii/mince) project.
 On clients it enables skins while the server connected to is running in Offline Mode, it is not required but strongly recommended.
 
 This mod is not meant to enable or otherwise facilitate piracy, rather as an alternative for players who have previously purchased the game and are dissatisfied with Microsoft's handling of the property.
