I'm new the startup world. I have a solid grasp of business principles and investing, but the details of the specific ways/methods of initial startup investments are fuzzy at best.

Are there any books or articles that the Hacker News community would recommend that explain in detail what they are and what to expect? For example, when is a convertible note a good option and when should the founder buy it back. Also, methods for determining fair equity stakes for early stage investments.

Thanks in advance. This community has already helped a lot!
