What are the various files clusterware reads to bring up clusterware

I want to understand which all files clusterware reads in order to start the clusterware up. Like, little bit I know is that OHASD reads OCL, and then GPNPprofile, and then somehow it reads ASM parameter file to get diskstrings and header to know which diskgroup has voting disk and such things. But not sure what are the other files and how it all works together start to end. Thanks.
