To install Uno by Cloud_Wolf, drag the "Uno" folder into your server folder. Then in the server properties file, make the resourcepack link:

https://www.dropbox.com/s/a5bb15zsyetbgya/UNO.zip?dl=1

then set the save to be "Uno". Then restart the server. For single player/LAN's, put the "Uno" folder under .minecraft>saves then have everyone download the resource pack from the above link. Put that .zip file directly under .minecraft>resource-packs

Thanks, and enjoy.
