How do I install this on 1.14.1? Install instruction are for 1.14 and not for 1.14.1 I am using MultiMC.

Fabric edition will be released, please wait for some hours.

Thanks for @ZekerZhayard , 1.14.x Fabric support is finished.
You can download it at CurseForge.

Thank you so much it works great! I was wondering is there any way to switch skin while in game trough a GUI or command?

Not supported now.
