+# Contributing
+
+Anyone and everyone is encouraged to contribute to this project. The most helpful changes are pull requests that fix one of the open issues in the Issues tab.
+Adding functionality that is available on the app/website but not through this interface is also very helpful. Grammar changes and changes to business logic
+that do not have a noticable effect on performance are generally not accepted.
+
+## Pull Request Process
+
+1. Make sure that if you make any grammar or documentation changes, that they are in a seperate commit from
+   any code changes.
+2. Make sure you update __init__.py to import new functions that are created.
+3. Make sure to update the version number in setup.py. The version number is in the format XX.YY.ZZ, where the
+   XX is only changed when there is a fundamental and major change, YY is changed for features added, and ZZ is changed
+   for bug fixes. When updating a number, all the numbers to the right get changed to zero. i.e. 1.23.50 => 1.24.0. Numbers
+   are also allowed to go as high as you want, so 1.65289.0 is a valid version number.
+4. After submitting a pull request, please be on the lookout for any messages from me about things that need to be fixed
+   before I merge the branch.

+## Code of Conduct

+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

+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.
