how do you build a ROM?

[r3v0]

I would like to build my very own ROM, any tutorials on how to?

i have Calkulin's Kitchen, and can piece the ROM together.

what i am really interested is how do i put certain programs that i want into the ROM, such as MaxManila. Then i would also want to build my own wallpaper and have it cooked into the ROM.

then icons and etc.
