What is the difference between a toolbox's release notes, user's guide, reference, and getting started guide?

For the Control System Toolbox there are four different help-like PDF documents:

1. Control System Toolbox Getting Started Guide
2. Control System Toolbox User's Guide
3. Control System Toolbox Reference
4. Control System Toolbox Release Notes

What is the difference between these documents?

[Azzi Abdelmalek]

1. Toolbox Getting Started Guide: Helps a beginner to be introduced to a toolbox
2. Toolbox User's Guide: contains all the details of your toolbox, illustrated with examples
3. Toolbox Reference: Should be a sorted list of functions, that explain those functions
4. Toolbox Release Notes: provides quick access to what's new in each version

And Reference: The DOC texts for each command.
