+## Encouraged Behaviors
+
+While acknowledging differences in social norms, we all strive to meet our
+community's expectations for positive behavior. We also understand that our
+words and actions may be interpreted differently than we intend based on
+culture, background, or native language.
+
+With these considerations in mind, we agree to behave mindfully toward each
+other and act in ways that center our shared values, including:
+
+1. Respecting the **purpose of our community**, our activities,
+   and our ways of gathering.
+2. Engaging **kindly and honestly** with others.
+3. Respecting **different viewpoints** and experiences.
+4. **Taking responsibility** for our actions and contributions.
+5. Gracefully giving and accepting **constructive feedback**.
+6. Committing to **repairing harm** when it occurs.
+7. Behaving in other ways that promote and sustain the
+   **well-being of our community**.
+
+## Restricted Behaviors
 
-Instances of abusive, harassing, or otherwise unacceptable behavior may be
-reported by contacting one of the project maintainers listed at
+We agree to restrict the following behaviors in our community. Instances,
+threats, and promotion of these behaviors are violations of this
+Code of Conduct.
+
+1. **Harassment.** Violating explicitly expressed boundaries or engaging in
+   unnecessary personal attention after any clear request to stop.
+2. **Character attacks.** Making insulting, demeaning, or pejorative comments
+   directed at a community member or group of people.
+3. **Stereotyping or discrimination.** Characterizing anyone’s personality or
+   behavior on the basis of immutable identities or traits.
+4. **Sexualization.** Behaving in a way that would generally be considered
+   inappropriately intimate in the context or purpose of the community.
+5. **Violating confidentiality**. Sharing or acting on someone's personal or
+   private information without their permission.
+6. **Endangerment.** Causing, encouraging, or threatening violence or other harm
+   toward any person or group.
+7. Behaving in other ways that **threaten the well-being** of our community.
+
+### Other Restrictions
+
+1. **Misleading identity.** Impersonating someone else for any reason, or
+   pretending to be someone else to evade enforcement actions.
+2. **Failing to credit sources.** Not properly crediting the sources of content
+   you contribute, including but not limited to the use of LLMs.
+3. **Promotional materials**. Sharing marketing or other commercial content in
+   a way that is outside the norms of the community.
+4. **Irresponsible communication.** Failing to responsibly present content which
+   includes, links or describes any other restricted behaviors.
+
+## Reporting an Issue
+
+Tensions can occur between community members even when they are trying their
+best to collaborate. Not every conflict represents a code of conduct violation,
+and this Code of Conduct reinforces encouraged behaviors and norms that can
+help avoid conflicts and minimize harm.
+
+When an incident does occur, it is important to report it promptly.
+
+To report a possible violation contact one of the project maintainers listed at
 https://rspec.info/about/. All complaints will be reviewed and investigated
 and will result in a response that is deemed necessary and appropriate to the
-circumstances. Maintainers are obligated to maintain confidentiality with
-regard to the reporter of an incident.
+circumstances.
+
+Maintainers take reports of violations seriously and will make every effort to
+respond in a timely manner. They will investigate all reports of code of conduct
+violations, reviewing messages, logs, and recordings, or interviewing witnesses
+and other participants. Maintainers will keep investigation and enforcement
+actions as transparent as possible while prioritizing safety and
+confidentiality. In order to honor these values, enforcement actions are carried
+out in private with the involved parties, but communicating to the whole
+community may be part of a mutually agreed upon resolution.
+
+## Addressing and Repairing Harm
+
+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.
+
+If an investigation that this Code of Conduct has been violated, the following
+enforcement ladder may be used to determine how best to repair harm, based on
+the incident's impact on the individuals involved and the community as a whole.
+Depending on the severity of a violation, lower rungs on the ladder may be
+skipped.
+
+1) Warning
+   1) Event: A violation involving a single incident or series of incidents.
+   2) Consequence: A private, written warning.
+   3) Repair: Examples of repair include a private written apology,
+      acknowledgement of responsibility, and seeking clarification on
+      expectations.
+
+2) Temporarily Limited Activities
+   1) Event: A repeated incidence of a violation that previously resulted in a
+      warning, or the first incidence of a more serious violation.
+   2) Consequence: A private, written warning with a time-limited cooldown
+      period designed to underscore the seriousness of the situation and give
+      the community members involved time to process the incident. The cooldown
+      period may be limited to particular communication channels or interactions
+      with particular community members.
+   3) Repair: Examples of repair may include making an apology, using the
+      cooldown period to reflect on actions and impact, and being thoughtful
+      about re-entering community spaces after the period is over.
+
+3) Temporary Suspension
+   1) Event: A pattern of repeated violation which have been issued warnings,
+      or a single serious violation.
+   2) Consequence: A private written warning with conditions for return from
+      suspension. In general, temporary suspensions give the person being
+      suspended time to reflect upon their behavior and possible corrective
+      actions.
+   3) Repair: Examples of repair include respecting the spirit of the
+      suspension, meeting the specified conditions for return, and being
+      thoughtful about how to reintegrate with the community when the suspension
+      is lifted.
+
+4) Permanent Ban
+   1) Event: A pattern of repeated code of conduct violations that other steps
+      on the ladder have failed to resolve, or a violation so serious that it
+      is determined there is no way to keep the community safe with this person
+      as a member.
+   2) Consequence: Access to all community spaces, tools, and communication
+      channels is removed. In general, permanent bans should be rarely used,
+      should have strong reasoning behind them, and should only be resorted to
+      if working through other remedies has failed to change the behavior.
+   3) Repair: There is no possible repair in cases of this severity.
+
+This enforcement ladder is intended as a guideline. It does not limit the
+ability of maintainers to use their discretion and judgment, in keeping
+with the best interests of our community.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public or other
+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.
