I've been confused on the right thing to do, as my computer is terrible and half the things I do to try and get in for Minecraft just don't load. can anyone help?
Once you download it (it should be a .zip file), open up Minecraft and click the button that says "Resource Packs". There should be a button that says Open Resource Pack Folder. Drag the .zip file into this folder. Close the resource packs menu, and click back into it. The new resource pack should be there.
