About the branches

The two branches of concern are master and releases. Master is where the action is, but the rides on that playground require Dist::Zilla. Seriously, you can't even run 'make test' in the master branch without the D.Z. If you fear/loathe/hate the D.Z, stick with the release branch.

The releases branch is automatically updated when new releases are made. It contains all the automatically generated files that the master branch doesn't, such as README, Makefile.PL, and Build.PL. It is identical to the distribution as you'd find it on CPAN, making it far easier for causual perl programmers to patch against.

Download the source

To make changes or submit patches, visit the URL above and click the Fork button. Then clone your fork to your local disk with this git command:

git clone git@github.com:YOUR-USER-NAME/mail-dmarc.git

Use the source

Use git as one would with most any VCS:

cd mail-dmarc

.... make a little change or two ...
git status       ( see changed files )
git diff         ( show differences )
git add          ( stage changes )
git commit

If your changes are significant in any way, and/or might possibly involve more than one commit, create a branch:

git checkout -b fix-knob-handle
... make changes ...
git commit
... make more related changes ...
git commit

When you are done with that branch, you can merge it back into the master branch:

git checkout master
git merge fix-knob-handle

When the new feature branch is no longer useful, delete it:

git branch -d fix-knob-handle

Submit your changes

git push origin master    (push to your GitHub account)

Visit your fork on the GitHub web site. On the main page of your fork is a Pull Request button. That is how you submit your changes to the main repo.

Check Mail::DMARC build status:

Travis automatically runs build tests when commits are pushed to GitHub, and sends notifications to the author(s) in case of failure. For everyone else, checking the build status after a push request is merged is a good idea.
