installation procedure's
if the mod isn't installed properly using the nmm then go into c:/programs (x86)/steam/steamapps/common/skyrim/data/textures/armor/nightingale and open the rar file and just drag and drop the 2 folder's into the nightingale folder and overwrite that should do the trick, be sure to make a backup of the folder's inside in case you want to uninstall my mod

credit goes to zerofrost for the initial mod and credit goes to ancientvampire for re-uploading it to the nexus so i could make the texture
