Your package name should reflect the scope of your project. Try to make sure your project is generally useful, without being too generally defined.
The primary code of your package should be in the src directory. This should also be the start of your PSR-0 autoload path, as a result the structure after src should contain a folder called CourseHero and then a folder with your package name.
This file should contain information about your project. This should have a brief clear instruction on the purpose of the project, how to install it, and how to use it.
