+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our
+community a harassment-free experience for everyone, regardless of age, body
+size, visible or invisible disability, ethnicity, sex characteristics, gender
+identity and expression, level of experience, education, socio-economic status,
+nationality, personal appearance, race, caste, color, religion, or sexual
+identity and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming,
+diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our
+community include:
+
+* Demonstrating empathy and kindness toward other people
+* Being respectful of differing opinions, viewpoints, and experiences
+* Giving and gracefully accepting constructive feedback
+* Accepting responsibility and apologizing to those affected by our mistakes,
+  and learning from the experience
+* Focusing on what is best not just for us as individuals, but for the overall
+  community
+
+Examples of unacceptable behavior include:
+
+* The use of sexualized language or imagery, and sexual attention or advances of
+  any kind
+* Trolling, insulting or derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or email address,
+  without their explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of
+acceptable behavior and will take appropriate and fair corrective action in
+response to any behavior that they deem inappropriate, threatening, offensive,
+or harmful.
+
+Community leaders 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, and will communicate reasons for moderation
+decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public spaces.
+Examples of representing our community include using an official email address,
+posting via an official social media account, or acting as an appointed
+representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported to the community leaders responsible for enforcement at
+[INSERT CONTACT METHOD].
+All complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the
+reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining
+the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed
+unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing
+clarity around the nature of the violation and an explanation of why the
+behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series of
+actions.
+
+**Consequence**: A warning with consequences for continued behavior. No
+interaction with the people involved, including unsolicited interaction with
+those enforcing the Code of Conduct, for a specified period of time. This
+includes avoiding interactions in community spaces as well as external channels
+like social media. Violating these terms may lead to a temporary or permanent
+ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including
+sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public
+communication with the community for a specified period of time. No public or
+private interaction with the people involved, including unsolicited interaction
+with those enforcing the Code of Conduct, is allowed during this period.
+Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community
+standards, including sustained inappropriate behavior, harassment of an
+individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within the
+community.
+

+# Reporting a security bug
+
+<!-- Note: Need to discuss this -->
+All security bugs in gotenberg should be reported to the core team through our private mailing list [selise@selisegroup.com]. Your report will be acknowledged within 24 hours, and you’ll receive a more detailed response to your email within 48 hours indicating the next steps in handling your report.
+
+After the initial reply to your report, the security team will endeavor to keep you informed of the progress being made towards a fix and full announcement. These updates will be sent at least every five days, although in practice, it is more likely to be every 24-48 hours.
+
+If you have not received a reply to your email within 48 hours, or have not heard from the security team for the past five days, there are a few steps you can take:
+
+## Disclosure Policy
+
+gotenberg follows a 5-step disclosure policy, which is upheld to the best of our ability.
+
+1. Security report received and is assigned a primary handler. This person will coordinate the fix and release process.
+2. Problem is confirmed and a list of all affected versions is determined. Code is audited to find any potential similar problems.
+3. Fixes are prepared for all releases which are still supported. These fixes are not committed to the public repository but rather held locally pending the announcement.
+4. A suggested embargo date for this vulnerability is chosen and distros@openwall is notified. This notification will include patches for all versions still under support and a contact address for packagers who need advice back-porting patches to older versions.
+5. On the embargo date, the [mailing list][mailing-list] and [security list][security-list] are sent a copy of the announcement. The changes are pushed to the public repository and new gems released to RubyGems.
+
+Typically, the embargo date will be set 72 hours from the time vendor-sec is first notified, however, this may vary depending on the severity of the bug or difficulty in applying a fix.
+
+This process can take some time, especially when coordination is required with maintainers of other projects. Every effort will be made to handle the bug in as timely a manner as possible, however, it’s important that we follow the release process above to ensure that the disclosure is handled in a consistent manner.
+
+## Security Updates
+
+Security updates will be posted on the [mailing list][mailing-list] and [security list][security-list].
+
+## Comments on this Policy
+
+If you have any suggestions to improve this policy, please email the core team at [selise@selisegroup.com].
+
+## Credit for Reporters
+
+We highly appreciate the efforts of security researchers who report vulnerabilities to us. We offer the following forms of recognition:
+
+TODO: Decide on these
+* Reporters will be listed on the project's official documentation site.
+* Reporters will be acknowledged in the security advisories and release notes associated with the fix.
+
+We strive to ensure that reporters receive due credit for their valuable contributions to the security of gotenberg.
