+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as contributors and maintainers pledge to making participation in our project and our community a harassment-free experience for everyone, regardless of age, body size, disability, ethnicity, gender identity and expression, level of experience, nationality, personal appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable behavior and are expected to take appropriate and fair corrective action in response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, or to ban temporarily or permanently any contributor for other behaviors that they deem inappropriate, threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces when an individual is representing the project or its community. Examples of representing a project or community include using an official project e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event. Representation of a project may be further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by contacting the project team at [email protected]. The project team will review and investigate all complaints, and will respond in a way that it deems appropriate to the circumstances. The project team is obligated to maintain confidentiality with regard to the reporter of an incident. Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good faith may face temporary or permanent repercussions as determined by other members of the project's leadership.

+# How to Contribute
+Thank you for contributing to aither! Check out the aither [blog](http://aithercfd.com) for more information. Aither
+uses the git flow branching method. The **master** branch is a permanent branch containing stable code with releases
+coming off of this branch. The default branch is the **develop** branch. This is a permanent branch containing the most 
+up-to-date code and is therefore not guaranteed to be working. Bug fixes and feature additions branch off of **develop** and 
+are merged back in when complete. Aither uses continuous integration services [TravisCI](https://travis-ci.org/mnucci32/aither) 
+and [Appveyor](https://ci.appveyor.com/project/mnucci32/aither/branch/develop) to test builds on Linux, macOS, and 
+Windows. The code is built on each platform and a suite of tests are run to ensure that the residuals have not 
+changed due to a commit. There are a few ways to get involved with this project including reporting or fixing a bug, 
+requesting or adding a feature, and adding documentation.
+
+### Reporting a Bug
+Bugs should be reported via [Github Issues](https://github.com/mnucci32/aither/issues).
+
+### Fixing a Bug
+A list of known bugs can be found on the [Issues](https://github.com/mnucci32/aither/issues) page. A fix can be submitted 
+by creating a new branch off of the **develop** branch with a descriptive name starting with **hotfix_**. When the bug has
+been fixed and and all continuous integration tests are passing, a pull request can be submitted to merge the fix back into
+**develop**.
+
+### Requesting a Feature
+New features should be requested via [Github Issues](https://github.com/mnucci32/aither/issues). Not all requests will be
+accepted.
+
+### Adding a Feature
+A list of features to be added can be found on the [Issues](https://github.com/mnucci32/aither/issues) page. If you want
+to add a feature not listed, first submit an issue requesting that it be added. New features should be implemented by 
+creating a branch off of **develop** with a descriptive name starting with **feature_**. When the feature has been fixed 
+and all continuous integreation tests are passing, a pull request can be submitted to merge the feature back into **develop**.
+If it is a fairly significant addition, an additional test case should be added as well.
+
+### Adding Documentation
+Documentation can be added by editing the [Wiki](https://github.com/mnucci32/aither/wiki) page.
+
+# Coding Style
+* Aither conforms to the [Google Style Guide](https://google.github.io/styleguide/cppguide.html)
+* Variable names should use camelCase starting with a lower case letter
+* Function names should use CamelCase starting with an upper case letter
+* Class member variables should be appended with a _
+* Modern C++ features should be used when possible

 * MPI - OpenMPI, MPICH, & MS-MPI have been used
 * C++ compiler with C++14 support
 * Cmake - Cmake only depends on a C++ compiler
