     74This project requires all contributors to assert that their contributions
     75are provided in compliance with the terms of the Developer's Certificate
     76of Origin 1.1 (DCO):
     77
     78  https://developercertificate.org/
     79
     80To indicate acceptance of the DCO every commit must have a tag
     81
     82  Signed-off-by: REAL NAME <EMAIL>
     83
     84This can be achieved by passing the "-s" flag to the "git commit" command.
     85
     86To bulk update all commits on current branch "git rebase" can be used:
     87
     88  git rebase -i master -x 'git commit --amend --no-edit -s'
