	Please signoff on all commits with your name, email and gpg key for the Developer's Certificate of Origin.
	`git config --global user.name your_name`
	`git config --global user.email you_email`
	COMMAND : `git commit -s -S -m your_commit_message`
	`-s` = `Signed-off-by`
	`-S` = `Verify commit using gpg key`
	If there is more than one commit in your pull request and your git client is modern enough (2.13+), rebase the required number of commits with --signoff:
	`git rebase --signoff -S HEAD~<number_of_commits>`
	Then, force push:
	`git push -f origin <your_branch>`
