Sorry, just a quick reply (got to run...), there is a sample .conf file on the same wiki page. Did you have look? You can edit it using notepad for example.
Every line with a # will be ignored. Lines without # will be processed.
Also, as mentioned before, what are you trying to achieve?
Its okay. I want to increase syncing speed with -dbcache ( something like that, I am in other computer, I don't remember the command correctly). Anyway thanks for helping!

Kindly,
Muhammed Zakhir
The bottleneck with synching is not your CPU but your bandwith. You can however speed up the starting proccess by lowering checkblocks from 288 to e.g. 100 or even 10.
