# How to contribute

* Make sure you have a [GitHub account](https://github.com/signup/free)
* Fork the repository on GitHub

## Making Changes

* Create a topic branch from where you want to base your work (this is almost
definitely the master branch).
  * To quickly create a topic branch based on master; `git branch
    fix/master/my_contribution master` then checkout the new branch with `git
    checkout fix/master/my_contribution`.
  * Please avoid working directly on the
    `master` branch.
* Make commits of logical units.
* Check for unnecessary whitespace with `git diff --check` before committing.
* Make sure your commit messages are in the proper format.

    Make the example in CONTRIBUTING imperative and concrete

    Without this patch applied the example commit message in the CONTRIBUTING
    document is not a concrete example.  This is a problem because the
    contributor is left to imagine what the commit message should look like
    based on a description rather than an example.  This patch fixes the
    problem by making the example concrete and imperative.

    The first line is a real life imperative statement with a ticket number
    from our issue tracker.  The body describes the behavior without the patch,
    why this is a problem, and how the patch fixes the problem when applied.

* Make sure you have added the necessary tests for your changes.
* Run _all_ the tests to assure nothing else was accidentally broken.
