Need help with compiling

Hi to all

I am relatively new to L2Off developing. But there is time for everything and I wanted to start with smth.

I have downloaded Smeli's Gracia Final L2Off server pack, and easily managed to start it up.

Thing is that I would like to add more NPC's, items etc.

I am aware of fact that I should use compilers and makers that are included in Smeli's pack, but when I try to insert something into Smeli's scripts, afterward I get L2Server crash and many errors while loading.

Is there any guide for compiling. I was trying to search, but all I can find is how to add 1 NPC or 1 Item.

I want to add multiply NPC's and etc.

Thanks
