Instructions for plugin development

I’m curious to hear about the possibilities of developing commercial plugins for Ghost. I see that you can develop and sell custom themes and Ghost have some integrations built in. Do you have some documentation about which possibilities I as a developer have to develop and sell plugins for Ghost?
