Rules of Thumb

• Every contribution is a piece of intellectual property.Please treat it with respect.
• Preserve both the name and email address.This is the precious sustenance that nourishes our project.
• Ensure your name and email address are there as the committer prior to pushing it to the Apache repositories.
• Always give credit where it is due, ensure every merged commit reflects properly the individual who authored that commit.

Setting up Your Repository

Clone the canonical ASF repo using this command. The --origin option tells git to name the remote apache instead of the default, 
origin; this will reduce ambiguity when we later add a second remote upstream.

git clone --origin apache https://git-wip-us.apache.org/repos/asf/incubator-corinthia.git

Add a second remote, for the GitHub repository.

git remote add github https://github.com/apache/incubator-corinthia.git

For the GitHub remote, add an additional fetch reference which will cause every pull request to be made available as a remote 
branch in your workspace.

{{git config --local --add remote.github.fetch '+refs/pull/*/head:refs/remotes/github/pr/*'}}

Finally, run git fetch --all to update from all remote repositories - you will see all the pull requests appear:

{{[new ref]         refs/pull/98/head -> github/pr/98
  * [new ref]         refs/pull/99/head -> github/pr/99}}

h3. Merging a pull request

                   <p>Fetch the latest remote branches, which will cause a remote branch for the PR to become available to you.
                   <div class="panel">git fetch --all</div>
                   If you want to inspect the PR and/or run tests, check out the branch:
                       <div class="panel">git checkout github/pr/1234</div>
                <p>To perform the merge, first update your master branch to the latest:</p>
                     <div class="panel">git checkout master   git pull --rebase</div>
                   <p>Then merge and push:</p>
                   <div class="panel">git merge --no-ff -m 'This closes #1234' github/pr/1234 git push apache master</div>
                   <p>Note that this commit message is important, as this is what will trigger the pull request to be automatically closed, and the --no-ff means that a
                   merge commit will always be created.</p>
               <h3>Alternative options</h3>
              <h4 class="subheader">Adding the remote reference to the contributor’s repository</h4>
              <p>Fetch the branch of the user you want to merge from
              <div class="panel">git fetch https://github.com/user-to-merge-from/incubator-corinthia.git branch-to-merge-from</div>
            <p>If you commonly merge from a particular user, you’ll want to add their repo as a remote to make fetching branches easier.</p>
             <div class="panel">git remote add user-to-merge-from https://github.com/user-to-merge-from/incubator-corinthia.git
             <br> git fetch user-to-merge-from</div>
               <h3>Merging from a patch file</h3>
             <p>Save the patch from the Github patch link (just append ‘.patch’ to the pull request link to get it). This patch will keep the authorship of the
            commit, so we should use it instead of the diff. Apply the patch preserving the original author:</p>
             <div class="panel">git am pull-request-9876.patch</div>
