Starter marketing guide for new app?

I've read a zillion books and articles, but now i need to actually do something.

I wonder if there is a simple one-page/250-word guide for how to promote my new app/service?

And maybe does it without subjecting me to an FBI-style interrogation about the details of my 'business'.

I guess I'm looking for something a bit more thoughtful than what I could come up with in the next 30 seconds, but prob not something that would take an expert more than a page and two minutes to type out.

Does such a thing exist?

In theory, maybe there are different levels to the guide(s). So, kindergarten level guide is one page, high school version is two pages, college is three pages, phd version is four pages.

Maybe there is some type of simple software that helps me manage the process. Maybe it's geared towards grumpy people like me who are not natural self-promoters.

But all that is just ideas -- I am just interested in a guide that covers the basics -- kind of like a checklist maybe. Here are the things you need to do once, here are the things you need to do daily, these things monthly, etc.

Thanks for ideas!
