I didn't have it in my readme file, but now I noticed that it depends on what version of server files you have. If you have native or viking conquest server files it won't have NW commands listed, because readme file doesn't come with the module. It comes with server files. That doesn't make sense to me, because if I had many different modules on my server I would have to download server files on my PC for each of them to get their readme files.
Thanks for help!
