Well first you need to download and install MySql. After you do that, create the db and password and associate info in the nwnx scripts. After that it just a matter of using the 3-5 nwnx scripting commands to read and write info to the db. The included documentation is very good. After that the only thing you need to learn are the SQL commands. Just type SQL commands in Google and you'll have no problem finding good documentation about the SELECT, INSERT etc commands.
