-## 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.

 Mastodon is a **free, open-source social network server** based on ActivityPub where users can follow friends and discover new ones. On Mastodon, users can publish anything they want: links, pictures, text, and video. All Mastodon servers are interoperable as a federated network (users on one server can seamlessly communicate with users from another one, including non-Mastodon software that implements ActivityPub!)

 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
-"Mastodon on local machine" container from the editor. The necessary `docker
-compose` commands to build and setup the container should run automatically. For
-**Visual Studio Code** this requires installing the [Dev Container extension].
-
-### GitHub Codespaces
-
-[GitHub Codespaces] provides a web-based version of VS Code and a cloud hosted
-development environment configured with the software needed for this project.
-
-[![Open in GitHub Codespaces](https://github.com/codespaces/badge.svg)][codespace]
-
-- Click the button to create a new codespace, and confirm the options
-- Wait for the environment to build (takes a few minutes)
-- When the editor is ready, run `bin/dev` in the terminal
-- Wait for an _Open in Browser_ prompt. This will open Mastodon
-- On the _Ports_ tab "stream" setting change _Port visibility_ → _Public_
