How to set up analytics for a startup?

Question

Google Analytics

Good afternoon. I launch a small application and, accordingly, a website for it. I want to track site usage, registration sources and other necessary things. Are there any manuals, instructions on how to set up such the most necessary things in google analytics? Something like a manual for a beginner startup about analytics :)?
Thank you!
