-## Request for information
-
-This project is still under development and is expected to be in such a state for a long turn.
-
-The ultimate goal of this project is to achive a **completely reliable** live simulation library which's outputs are completely match in-game live results. For the sake of that, to ensure outputs are completely reliable, a large amount of comparative experiments are indispensable during the whole development lifecycle. Even if I will do that at a slow pace it still would be difficult to cover all the situations. That said, the more helps or informations there are, the more acurrate results will be.  
-Welcome to commit issues if you find any incorrect results while using this library.
