+- modify the Hack source in your local clone of the Hack repository, commit all files, replace all `*plist` files with the upstream versions then perform a git squash commit to eliminate the `*.plist` file changes in the git history (this approach can be used for those who didn't read the instructions and have already commited unacceptable file changes)

+Contributions to the project come in many forms and we **want** to broadly acknowledge those who spend time and effort to improve the project.  We understand that many contributions to open source projects are not in the form of changes to the code base and therefore not automatically recognized in the Github repository UI.  Use case specialists play an extremely important role in the improvement of this typeface.  Individuals who have knowledge of the intricacies of open source typeface licensing, understand open source project redistribution processes, have the capacity to view errors and test in unique platform x font renderer situations, and many other areas that extend beyond the "source code commit" criterion have contributed their expertise to improve Hack. Understanding this issue, we maintain a [CONTRIBUTORS.md](docs/CONTRIBUTORS.md) list to acknowledge project contributors for their time and efforts under our own defintion of a project contribution.
