+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining

+
+### 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

-## 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.
 
 Example:
 
-|Not ideal|Better|
-|---|----|
-|Fixed NoMethodError in RemovalWorker|Fix nil error when removing statuses caused by race condition|
+| Not ideal                            | Better                                                        |
+| ------------------------------------ | ------------------------------------------------------------- |
+| Fixed NoMethodError in RemovalWorker | Fix nil error when removing statuses caused by race condition |
 
-It is not always possible to phrase every change in such a manner, but it is desired.
+### Technical Requirements
 
-**The smaller the set of changes in the pull request is, the quicker it can be reviewed and merged.** Splitting tasks into multiple smaller pull requests is often preferable.
+Pull requests that do not pass automated checks on CI may not be reviewed. In
+particular, please keep in mind:
 
-**Pull requests that do not pass automated checks may not be reviewed**. In particular, you need to keep in mind:

+## ActivityPub in Mastodon
 
 Mastodon largely follows the ActivityPub server-to-server specification but it makes uses of some non-standard extensions, some of which are required for interacting with Mastodon at all.

 ### Required extensions
 
-#### Webfinger
+#### WebFinger
 
 In Mastodon, users are identified by a `username` and `domain` pair (e.g., `Gargron@mastodon.social`).
 This is used both for discovery and for unambiguously mentioning users across the fediverse. Furthermore, this is part of Mastodon's database design from its very beginnings.
 
 As a result, Mastodon requires that each ActivityPub actor uniquely maps back to an `acct:` URI that can be resolved via WebFinger.
