I want to know, if I can use this mod in my modpack,
because your license doesn't say it clearly.
I hope to get an answer soon.

same goes for zeherlib

Thanks for the fast answer I really love this mod.
Also I was going to link to you even in my private modpack.

Yes of course you can use my mod in your modpack, as long as it is private. If it is public then there are requirements, such as linking to the modpage and ensuring I am named as the author.

Not a problem. Glad you like the mod!
