I don't really have anything to write here, so how about a little install instruction?

1. install dsfix and configure it for your computer.
2. enable texture overwrite in dsfix.ini by setting it to 1
3. unpack the textures you want and move them to:*Steam\SteamApps\common\Dark Souls Prepare to Die Edition\DATA\dsfix\tex_override
4. enjoy.

or you can just use the Nexus Mod Manager. It should be compatible, I think.
