when my commit will be merged?

@nyilynnhtwe Heyo, thanks for catching these. This repo requires that contributors have verified commits set up before we can merge PRs. Can you set up commit verification? Instructions: https://docs.github.com/en/authentication/managing-commit-signature-verification/about-commit-signature-verification

If you want us to merge this, you'll have to set that up and possibly rebase the old commits to be verified.
