Is there a HOWTO on the subject of "creating my own board configuration"?

Do I put hooks in "make menuconfig" to enable/disable my customizations? 

I'm new to the process of building kernels, and I have been using an
off-the-shelf development board that had a supported configuration, so
my only customizations have been turning on/off preconfigured options. 
Any guidance, or the name of a more appropriate list in which to
post the question would be appreciated.

Thanks,

Ed
