Please include a tutorial on how to use your product.

An example of this:

I saw a talk on FiloDB. It sounds like an interesting time series collection database. The technical challenges sound interesting and the architecture sounds like its sensible. However, when going to the project, there’s nothing there that will get me off the ground and working with it quickly.

TL;DR Write documentation in a manner which it helps to lead the user to use your product/project successfully.
