FAQ

Q: Will it be kept to latest version?
A: No. We'd better check version of libraries you need manually. Then choose the appropriate version for your project. But I still update it occasionally.

Q: Can I contribute some code?
A: I'm sorry that this file will be only maintained by myself. Of course you still can comment it with your idea.
