Hi all SRPers

I have finally decided to hone my own razors so have invested in a Naniwa 12000 speciality stone with holder and Nagura stone. I know there is a lot of information out there about honing most of which I have read about, videos and how to's all watched. At this moment in time my primary interest is to master just keeping my razors sharp using this stone, I don't intend to start any renovation of poor edges yet. I have noticed that there are a few minor imperfections on the surface of the 12000 stone and wanted to know the exact process of ensuring the surface is flat using the nagura stone. The Nagura stone has rough corners to it also. Will it be okay to use the Nagura with these slightly rough edges and should I use it wet or dry? I have seen the Nagura stones being used both wet and dry and to be completely honest I think Iv'e seen that much now that I'm still non the wiser. Can someone put it in really simple terms exactly what I should be doing to get this stone into a condition for my first attempt at honing. Thanks.
