+# 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 via email to
+simon@fdpl.io. All complaints will be reviewed and investigated fairly
+and as soon as personal time and energy of community leaders permits.
+
+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.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant](https://www.contributor-covenant.org),
+version 2.1, available at
+[https://www.contributor-covenant.org/version/2/1/code_of_conduct.html](https://www.contributor-covenant.org/version/2/1/code_of_conduct.html).
+
+Community Impact Guidelines were inspired by
+[Mozilla's code of conduct enforcement ladder](https://github.com/mozilla/diversity).

 Make your events more discoverable, expand your reach effortlessly while being independent of other (commercial) platforms, and be a part of the growing decentralized web (the Fediverse).

 Forget the hassle of managing multiple social media accounts just to keep your audience informed.
 
 This plugin is not an event managing plugin but an add-on to popular event plugins. It extends their functionality to fully support the [ActivityPub plugin](https://wordpress.org/plugins/activitypub/).
 With the ActivityPub plugin people can follow your website directly and engage with your events just as they would on social media: liking, boosting and even commenting if you enable it.
 You retain full ownership of your content. By integrating into your existing setup, it ensures no extra work is needed while enhancing your events' visibility across the web.
 
-### How It Works
+### How It Works ###
 
 With the ActivityPub Event Bridge WordPress plugin, sharing your events is effortless and automatic!
 Once you create an event on your WordPress site, it is seamlessly shared across the decentralized web using the ActivityPub protocol.

 </p>
 
 Your events can be automatically delivered to platforms that fully support events, such as [Mobilizon](https://joinmobilizon.org/), [Gancio](https://gancio.org), [Friendica](https://friendi.ca), [Hubzilla](https://hubzilla.org), and [Pleroma](https://pleroma.social/).
 These platforms create public event calendars by pulling in events from various sources, including your website. Any updates you make to your events are synced across these platforms—so you only need to manage your events on your own site, with no extra work required.

 </p>
 
 Even platforms that don't yet fully support events, like [Mastodon](https://joinmastodon.org), will still receive a detailed, well-composed summary of your event.
 The Event Federation plugin ensures that users from those platforms are provided with all important information about an event.

 **Automatic Event Summaries:** When your event is shared on the Fediverse, platforms like Mastodon that don't fully support events will display a brief HTML summary of key details — such as the event's title, start time, and location. This ensures that even if someone can't view the full event on their platform, they still get the important info at a glance, with a link to your WordPress event page.

 **Event Reminders for Your Followers:** Often, events are planned well in advance. To keep your followers informed right in time, you can set up reminders that are supposed to trigger the events showing up in their timelines right before the event starts. At the moment this reminder is implemented as a self-boost of your original event post. While this feature may behave differently across various platforms, we are working on a more robust solution that will let you schedule dedicated reminder notes that appear in all followers' timelines.

-### Do I need to install another event plugin to use the Event Federation plugin?
 
 Yes, this plugin works as an add-on and requires both the ActivityPub plugin and a supported event plugin such as The Events Calendar, VS Event List, or Events Manager to manage your events. It just fills the missing gap between event plugins and the [ActivityPub plugin](https://wordpress.org/plugins/activitypub/).
