This template was initially based off a few generally accepted decks that were passed to me by friends who were / are VC's, I then based this on years experience in the entrepreneurship space building, growing and selling companies, added a few things that I believed to be improvements in communicating value to your potential investors.
This is also not a bible but should serve to give an overview of what you should think about. Each company and business is different, think about those items in this deck that are important to your business and use them. It's also ugly on purpose, so you have to do the work putting it all together.
By all means, edit, augment, change as you see fit. Enjoy, and good luck!
