# How it works

> Plain explanations of how Re:InvestorHub behaves: why a number changes, what a stage means, and what your plan and role allow.

These pages explain what Re:InvestorHub does as you work, not which buttons to press. Read one when a number surprises you, when you want to know what a move will change, or when you want to understand a limit before you hit it.
