+# 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 support@cryptomator.org. 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 [http://contributor-covenant.org/version/1/4][version]

 ## Features
-- Totally transparent: Just work on the encrypted volume, as if it was an USB flash drive
-- Works with Dropbox, OneDrive (Skydrive), Google Drive and any other cloud storage, that syncs with a local directory.
-- In fact it works with any directory. You can use it to encrypt as many folders as you like
+
+- Works with Dropbox, Google Drive, OneDrive, and any other cloud storage service that synchronizes with a local directory
+- Open Source means: No backdoors, control is better than trust
+- Client-side: No accounts, no data shared with any online service
+- Totally transparent: Just work on the virtual drive as if it were a USB flash drive
 - AES encryption with 256-bit key length
-- Client-side. No accounts, no data shared with any online service
-- Filenames get encrypted too
-- No need to provide credentials for any 3rd party service
-- Open Source means: No backdoors. Control is better than trust
-- Use as many encrypted folders in your Dropbox as you want. Each having individual passwords
-- No commercial interest, no government agency, no wasted taxpayers' money ;-)
+- Filenames get encrypted, too
+- Use as many vaults in your Dropbox as you want, each having individual passwords
 
 ### Privacy
-- 256 bit keys (unlimited strength policy bundled with native binaries - 128-bit elsewhere)

 - Lightweight: [Complexity kills security](https://www.schneier.com/essays/archives/1999/11/a_plea_for_simplicit.html)
 
 ### Consistency

 - HMAC over file contents to recognize changed ciphertext before decryption
-- I/O operations are transactional and atomic, if the file systems support it
-- Each file contains all information needed for decryption (except for the key of course). No common metadata means no [SPOF](http://en.wikipedia.org/wiki/Single_point_of_failure)
