-# Contributor Covenant Code of Conduct
+# Contributor Covenant 3.0 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 make our community welcoming, safe, and equitable for all.
 
-We pledge to act and interact in ways that contribute to an open, welcoming,
-diverse, inclusive, and healthy community.
+We are committed to fostering an environment that respects and promotes the dignity, rights, and contributions of all individuals, regardless of characteristics including race, ethnicity, caste, color, age, physical characteristics, neurodiversity, disability, sex or gender, gender identity or expression, sexual orientation, language, philosophy or religion, national or social origin, socio-economic position, level of education, or other status. The same privileges of participation are extended to everyone who participates in good faith and in accordance with this Covenant.
 
-## Our Standards
+## Encouraged Behaviors
 
-Examples of behavior that contributes to a positive environment for our
-community include:
+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.
 
-- 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
+With these considerations in mind, we agree to behave mindfully toward each other and act in ways that center our shared values, including:
 
-Examples of unacceptable behavior include:
+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**.
 
-- 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
+## Restricted Behaviors
 
-## Enforcement Responsibilities
+We agree to restrict the following behaviors in our community. Instances, threats, and promotion of these behaviors are violations of this Code of Conduct.
 
-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.
+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.
 
-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.
+### 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.
+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, send an email describing the situation to hello@joinmastodon.org.
+
+Community Moderators 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. Community Moderators 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
+
+If an investigation by the Community Moderators finds 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 from the Community Moderators.
+   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 the Community Moderators have tried to address with 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 the Community Moderators determine 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 Community Managers 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 spaces.
-Examples of representing our community include using an official e-mail 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
-[hello@joinmastodon.org](mailto:hello@joinmastodon.org).
-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.
+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.

-## Pull requests
+## Pull Requests
 
-**Please use clean, concise titles for your pull requests.** Unless the pull request is about refactoring code, updating dependencies or other internal tasks, assume that the person reading the pull request title is not a programmer or Mastodon developer, but instead a Mastodon user or server administrator, and **try to describe your change or fix from their perspective**. We use commit squashing, so the final commit in the main branch will carry the title of the pull request, and commits from the main branch are fed into the changelog. The changelog is separated into [keepachangelog.com categories](https://keepachangelog.com/en/1.0.0/), and while that spec does not prescribe how the entries ought to be named, for easier sorting, start your pull request titles using one of the verbs "Add", "Change", "Deprecate", "Remove", or "Fix" (present tense).
+### Size and Scope
+
+Our time is limited and PRs making large, unsolicited changes are unlikely to
+get a response. Changes which link to an existing confirmed issue, or which come
+from a "help wanted" issue or other request, are more likely to be reviewed.
+
+The smaller and more narrowly focused the changes in a PR are, the easier they
+are to review and potentially merge. If the change only makes sense in some
+larger context of future ongoing work, note that in the description, but still
+aim to keep each distinct PR to a "smallest viable change" chunk of work.
+
+### Description of Changes
+
+Unless the Pull Request is about refactoring code, updating dependencies or
+other internal tasks, assume that the audience are not developers, but a
+Mastodon user or server admin, and try to describe it from their perspective.
+
+The final commit in the main branch will carry the title from the PR. The main
+branch is then fed into the changelog and ultimately into release notes. We try
+to follow the [keepachangelog] spec, and while that does not prescribe how
+exactly the entries ought to be named, starting titles using one of the verbs
+"Add", "Change", "Deprecate", "Remove", or "Fix" (present tense) is helpful.

+## Size limits
+
+Mastodon imposes a few hard limits on federated content.
+These limits are intended to be very generous and way above what the Mastodon user experience is optimized for, so as to accommodate future changes and unusual or unforeseen usage patterns, while still providing some limits for performance reasons.
+The following table summarizes those limits.
+
+| Limited property                                              | Size limit | Consequence of exceeding the limit |

-### No vendor lock-in: Fully interoperable with any conforming platform
+**Part of the Fediverse. Based on open standards, with no vendor lock-in.** - the network goes beyond just Mastodon; anything that implements ActivityPub is part of a broader social network known as [the Fediverse](https://jointhefediverse.net/). You can follow and interact with users on other servers (including those running different software), and they can follow you back.
 
-It doesn't have to be Mastodon; whatever implements ActivityPub is part of the social network! [Learn more](https://blog.joinmastodon.org/2018/06/why-activitypub-is-the-future/)
+**Real-time, chronological timeline updates** - updates of people you're following appear in real-time in the UI.
 
-### Real-time, chronological timeline updates
+**Media attachments** - upload and view images and videos attached to the updates. Videos with no audio track are treated like animated GIFs; normal videos loop continuously.
 
-Updates of people you're following appear in real-time in the UI via WebSockets. There's a firehose view as well!
+**Safety and moderation tools** - Mastodon includes private posts, locked accounts, phrase filtering, muting, blocking, and many other features, along with a reporting and moderation system.

 ## Deployment
 
 ### Tech stack
 
-- **Ruby on Rails** powers the REST API and other web pages
-- **React.js** and **Redux** are used for the dynamic parts of the interface
-- **Node.js** powers the streaming API
+- [Ruby on Rails](https://github.com/rails/rails) powers the REST API and other web pages.
+- [PostgreSQL](https://www.postgresql.org/) is the main database.
+- [Redis](https://redis.io/) and [Sidekiq](https://sidekiq.org/) are used for caching and queueing.
+- [Node.js](https://nodejs.org/) powers the streaming API.
+- [React.js](https://reactjs.org/) and [Redux](https://redux.js.org/) are used for the dynamic parts of the interface.
+- [BrowserStack](https://www.browserstack.com/) supports testing on real devices and browsers. (This project is tested with BrowserStack)

-The repository includes deployment configurations for **Docker and docker-compose** as well as specific platforms like **Heroku**, and **Scalingo**. For Helm charts, reference the [mastodon/chart repository](https://github.com/mastodon/chart). The [**standalone** installation guide](https://docs.joinmastodon.org/admin/install/) is available in the documentation.
-
-## Development
-
-### Vagrant
-
-A **Vagrant** configuration is included for development purposes. To use it, complete the following steps:
-
-- Install Vagrant and Virtualbox
-- Install the `vagrant-hostsupdater` plugin: `vagrant plugin install vagrant-hostsupdater`
-- Run `vagrant up`
-- Run `vagrant ssh -c "cd /vagrant && bin/dev"`
-- Open `http://mastodon.local` in your browser
-
-### macOS
-
-To set up **macOS** for native development, complete the following steps:
-
-- Install [Homebrew] and run `brew install postgresql@14 redis imagemagick
-libidn nvm` to install the required project dependencies
-- Use a Ruby version manager to activate the ruby in `.ruby-version` and run
-  `nvm use` to activate the node version from `.nvmrc`
-- Run the `bin/setup` script, which will install the required ruby gems and node
-  packages and prepare the database for local development
-- Finally, run the `bin/dev` script which will launch services via `overmind`
-  (if installed) or `foreman`
-
-### Docker
-
-For production hosting and deployment with **Docker**, use the `Dockerfile` and
-`docker-compose.yml` in the project root directory.
-
-For local development, install and launch [Docker], and run:
-
-```shell
-docker compose -f .devcontainer/compose.yaml up -d
-docker compose -f .devcontainer/compose.yaml exec app bin/setup
-docker compose -f .devcontainer/compose.yaml exec app bin/dev
-```
-
-### Dev Containers
-
-Within IDEs that support the [Development Containers] specification, start the
