     74 This project requires all contributors to assert that their contributions
     75 are provided in compliance with the terms of the Developer's Certificate
     76 of Origin 1.1 (DCO):
     77 
     78   https://developercertificate.org/
     79 
     80 To indicate acceptance of the DCO every commit must have a tag
     81 
     82   Signed-off-by: REAL NAME <EMAIL>
     83 
     84 This can be achieved by passing the "-s" flag to the "git commit" command.
     85 
     86 To 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'
