Step 1 is to learn the syntax of the Pawn language, you cannot begin exploring what modules do (hamsandwich, fakemeta, cstrike) or begin doing anything useful until you understand how code at the highest level (syntax, formatting, structure). Pawn is somewhat similar to C for the basic syntax, but if you look for C tutorials you'll likely get needlessly confused. Hunt down the Pawn Language Guide, that may help, at the same time it may be too much but good to have in your back pocket.

I'd begin with looking at existing plugins from these forums to get a feel for how to code and then begin experimenting on your own. Download the HLDS (dedicated server) onto your PC, set up AMX-X Studio to compile locally to that, and then add a test plugin that you are working on in plugins.ini and then keep experimenting with stuff until you figure it out.
