Hi there! This is the readme for the Crystal Sun Sword mod by catflop/sad maryam/aliceface depending on where you got it.

Installation is simple; though I have not tested it, NMM installation should work, and otherwise, simply extract the .zip file to your skyrim/data folder.

If you want to delete it afterwards, simply remove the following files:

data/crystalsuncombo.esp
data/meshes/weapons/crystalsun/crystalsun.nif
data/meshes/weapons/crystalsun/crystalsunold.nif
data/meshes/weapons/crystalsun/crystalsun2hand.nif
data/textures/weapons/crystalsun/crystalsun.dds
data/textures/weapons/crystalsun/crystalsunold.dds
data/textures/weapons/crystalsun/crystalsun_n.dds
data/textures/weapons/crystalsun/crystalsunold_n.dds
data/textures/weapons/crystalsun/crystalsun_m.dds
data/textures/weapons/crystalsun/crystalsunold_m.dds
and this readme file.

Once installed (and checked in the launcher/NMM so it loads), the sword should be in game. If you don't want to go to the trouble of finding it randomly, it is in:

~SPOILERS~

Lost Echo Cave, west of Solitude 

map here:

You'll find 2 swords of there, along with a worn note giving you instructions on how to smith them into better versions (both a one handed and 2 handed recipe are added).

Have fun, and I hope you like it!
