+# 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

+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 max.goedjen@gmail.com. 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.

+# Contributing to Secretive
+
+Thanks for your interest in contributing to Secretive! Before you contribute, there are a few things I'd like to lay out.
+
+## Security
+
+Security is obviously paramount for a project like Secretive. As such, any contributions that compromise the security or auditabilty of the project will be rejected.
+
+### Dependencies
+
+Secretive is desigend to be easily auditable by people who are considering using it. In keeping with this, Secretive has no third party dependencies, and any contributions which bring in new dependencies will be rejected.
+
+## Code of Conduct
+
+All contributors must abide by the [Code of Conduct](CODE_OF_CONDUCT.md)
+
+## Secretive is Opinionated
+
+I'm releasing Secretive as open source so that other people can use it and audit it, feeling comfortable in knowing that the source is available so they can see what it's doing. I have a pretty strong idea of what I'd like this project to look like, and I may respectfully decline contributions that don't line up with that vision. If you'd like to propose a change before implementing, please feel free to [Open an Issue with the proposed tag](https://github.com/maxgoedjen/secretive/issues/new?labels=proposed).

 ### Security Considerations
 
-For the moment, you must build Secretive from source. For an app like this, it's critical that you trust that the app you're running is the app whose source you've checked out. To this end, Secretive has no third party dependecies, and is designed to be easy for you to audit for exploits.
+Builds are produced by GitHub Actions with an auditable build and release generation process. Each build has a "Document SHAs" step, which will output SHA checksums for the build produced by the GitHub Action, so you can verify that the source code for a given build corresponds to any given release.
 
 ### A Note Around Code Signing and Keychains

 ### Backups and Transfers to New Machines
 
 Beacuse secrets in the Secure Enclave are not exportable, they are not able to be backed up, and you will not be able to transfer them to a new machine. If you get a new Mac, just create a new set of secrets specific to that Mac.
