📚 Documentation: App class documentation is not up to date

[zvikfir]

💭 Description

Both the README.md file and the Getting-Starting-Guide.md file suggests that there are 3 types of hooks, and that the parameters for the init hook for example are a callback function, a resources array, and a group.

However, this has not been the case for the past 2 years.

Documentation should be updated.
