Any input would be great. topic

So when I heard the bad news bout our great dev was thinking bout stepping down I wanted to fig out how to make a ota stock Rom zip for next update incase the dev is really gone. So far I extracted the ota which gave me my firmware zip. Then I got my fastboot.exe an adb.exe. so my question is I want to know if that all I need once I put them together is that only 3 things I need. I only researched for about 5 hours last night to come up with all that..Any input would be sweet.
