+# 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 oss@gchq.gov.uk. 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.
+
+## 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]

 #### *The Cyber Swiss Army Knife*
 
-CyberChef is a simple, intuitive web app for carrying out all manner of "cyber" operations within a web browser. These operations include creating hexdumps, simple encoding like XOR or Base64, more complex encryption like AES, DES and Blowfish, data compression and decompression, calculating hashes and checksums, IPv6 and X.509 parsing, and much more.
+CyberChef is a simple, intuitive web app for carrying out all manner of "cyber" operations within a web browser. These operations include simple encoding like XOR or Base64, more complex encryption like AES, DES and Blowfish, creating binary and hexdumps, compression and decompression of data, calculating hashes and checksums, IPv6 and X.509 parsing, changing character encodings, and much more.
 
-The tool is designed to enable both technical and non-technical analysts to manipulate data in complex ways without having to deal with complex tools or algorithms. It was conceived, designed, built and incrementally improved by an analyst in their 10% innovation time over several years. Every effort has been made to structure the code in a readable and extendable format, however it should be noted that the analyst is not a professional developer and the code has not been peer-reviewed for compliance with a formal specification.

  - Drag and drop

-     - Files can be dragged over the input box to load them directly.

      - This can be turned off and operated manually if it is affecting performance (if the input is very large, for instance).
-     - If any bake takes longer than 200 milliseconds, auto bake will be switched off automatically to prevent further performance issues.
  - Breakpoints
      - You can set breakpoints on any operation in your recipe to pause execution before running it.
      - You can also step through the recipe one operation at a time to see what the data looks like at each stage.
  - Save and load recipes
-     - If you come up with an awesome recipe that you know you’ll want to use again, just click save and add it to your local storage. It'll be waiting for you next time you visit CyberChef.
-     - You can also copy a URL which includes your recipe and input which can be shared with others.

  - Search
      - If you know the name of the operation you want or a word associated with it, start typing it into the search field and any matching operations will immediately be shown.
  - Highlighting
-     - When you highlight text in the input or output, the offset and length values will be displayed and, if possible, the corresponding data will be highlighted in the output or input respectively (example: [highlight the word 'question' in the input to see where it appears in the output][8]).

  - Save to file and load from file
-     - You can save the output to a file at any time or load a file by dragging and dropping it into the input field (note that files larger than about 500kb may cause your browser to hang or even crash due to the way that browsers handle large amounts of textual data).
+     - You can save the output to a file at any time or load a file by dragging and dropping it into the input field. Files up to around 500MB are supported (depending on your browser), however some operations may take a very long time to run over this much data.
  - CyberChef is entirely client-side
-     - It should be noted that none of your input or recipe configuration is ever sent to the CyberChef web server - all processing is carried out within your browser, on your own computer.
-     - Due to this feature, CyberChef can be compiled into a single HTML file. You can download this file and drop it into a virtual machine, share it with other people, or use it independently on your desktop.
