+# 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, sex characteristics, gender identity and expression,
+level of experience, education, socio-economic status, 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 through GitHub. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and 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.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
+available at https://www.contributor-covenant.org/version/1/4/code-of-conduct.html

+2. [Github - Signing-Commits](https://help.github.com/articles/signing-commits/)
+3. [Yubikey Git Signing](https://developers.yubico.com/PGP/Git_signing.html)
+
+## Contribution Process
+
+The following are the general steps for a contribution:
+
+1. Commit changes to a git branch, making sure to use commit signing.
+2. Create a GitHub Pull Request for your change, following the instructions in the pull request template.
+
+### Pull Request Requirements
+
+The following requirements exist for pull requests:
+
+1. Commits are signed.
+2. PR follows template.
+3. CI build and tests pass.

+
+Code review takes place in GitHub pull requests. See [this article](https://help.github.com/articles/about-pull-requests/) if you're not familiar with GitHub Pull Requests.
+
+Once you open a pull request, a code review will take place within the files changed of your PR. An approval, comment, or request for changes will be responded on the PR to further the request.

 For a production deployment of moodle, use of a FQDN is advised. This FQDN should be created in DNS for resolution to your host. For example, if your internal DNS is company.com, you could leverage moodle.company.com and have that record resolve to the host running your moodle container. The moodle url would then be, `MOODLE_URL=http://moodle.company.com`
 In the following steps, replace MOODLE_URL with your appropriate FQDN.
