 * Please use the -s option in git to "sign off" that the commit is your work and you are providing it under the Apache 2.0 License
 * Submit a Github Pull Request to the appropriate branch and ideally discuss the changes with us in IRC.
 * We will look at the patch, test it out, and give you feedback.
 * Avoid doing minor whitespace changes, renamings, etc. along with merged content. These will be done by the maintainers from time to time but they can complicate merges and should be done seperately.
 * Take care to maintain the existing coding style.
+* `go fmt` your code.
 * Add unit tests for any new or changed functionality.
 * All pull requests should be "fast forward"
   * If there are commits after yours use “git rebase -i <new_head_branch>”
